AccessEntity 政策

For related information, see What you need to know about policy errors and Handling faults.

Runtime errors

None.

Deployment errors

Error name Fault string HTTP status Occurs when
InvalidEntityType Invalid type [entity_type] in ACCESSENTITYStepDefinition [policy_name] N/A The entity type used must be one of the supported types.

AssignMessage 政策

This section describes the fault codes and error messages that are returned and fault variables that are set by Edge when this policy triggers an error. This information is important to know if you are developing fault rules to handle faults. To learn more, see What you need to know about policy errors and Handling faults.

Runtime errors

These errors can occur when the policy executes.

Fault code HTTP status Cause Fix
steps.assignmessage.SetVariableFailed 500 The policy was not able to set a variable. See the fault string for the name of the unresolved variable.
steps.assignmessage.VariableOfNonMsgType 500

This error occurs if the source attribute in the <Copy> element is set to a variable which is not of type message.

Message type variables represent entire HTTP requests and responses. The built-in Edge flow variables request, response, and message are of type message. To learn more about message variables, see the Variables reference.
steps.assignmessage.UnresolvedVariable 500

This error occurs if a variable specified in the Assign Message policy is either:

  • out of scope (not available in the specific flow where the policy is being executed)
    • or
  • can't be resolved (is not defined)

Deployment errors

These errors can occur when you deploy a proxy containing this policy.

Error name Cause Fix
InvalidIndex If the index specified in the <Copy> and/or <Remove> elements of the Assign Message policy is 0 or a negative number, then deployment of the API Proxy fails.
InvalidVariableName If the child element <Name> is empty or not specified in the <AssignVariable> element, then the deployment of the API proxy fails because there is no valid variable name to which to assign a value. A valid variable name is required.
InvalidPayload A payload specified in the policy is invalid.

Fault variables

These variables are set when this policy triggers an error at runtime. For more information, see What you need to know about policy errors.

Variables Where Example
fault.name="fault_name" fault_name is the name of the fault, as listed in the Runtime errors table above. The fault name is the last part of the fault code. fault.name Matches "UnresolvedVariable"
assignmessage.policy_name.failed policy_name is the user-specified name of the policy that threw the fault. assignmessage.AM-SetResponse.failed = true

Example error response

{  
   "fault":{  
      "detail":{  
         "errorcode":"steps.assignmessage.VariableOfNonMsgType"
      },
      "faultstring":"AssignMessage[AM-SetResponse]: value of variable is not of type Message"
   }
}

Example fault rule

    <FaultRule name="Assign Message Faults">    <Step>
        <Name>AM-CustomNonMessageTypeErrorResponse</Name>
        <Condition>(fault.name Matches "VariableOfNonMsgType") </Condition>
    </Step>
    <Step>
        <Name>AM-CustomSetVariableErrorResponse</Name>
        <Condition>(fault.name = "SetVariableFailed")</Condition>
    </Step>
    <Condition>(assignmessage.failed = true) </Condition>
</FaultRule>

BasicAuthentication 政策

This section describes the fault codes and error messages that are returned and fault variables that are set by Edge when this policy triggers an error. This information is important to know if you are developing fault rules to handle errors. To learn more, see What you need to know about policy errors and Handling faults.

Runtime errors

These errors can occur when the policy executes.

Fault code HTTP status Cause Fix
steps.basicauthentication.InvalidBasicAuthenticationSource 500 On a decode when the incoming Base64 encoded string does not contain a valid value or the header is malformed (e.g., does not start with "Basic").
steps.basicauthentication.UnresolvedVariable 500 The required source variables for the decode or encode are not present. This error can only occur if IgnoreUnresolvedVariables is false.

Deployment errors

These errors can occur when you deploy a proxy containing this policy.

Error name Occurs when Fix
UserNameRequired The <User> element must be present for the named operation.
PasswordRequired The <Password> element must be present for the named operation.
AssignToRequired The <AssignTo> element must be present for the named operation.
SourceRequired The <Source> element must be present for the named operation.

Fault variables

These variables are set when a runtime error occurs. For more information, see What you need to know about policy errors.

Variables Where Example
fault.name="fault_name" fault_name is the name of the fault, as listed in the Runtime errors table above. The fault name is the last part of the fault code. fault.name Matches "UnresolvedVariable"
BasicAuthentication.policy_name.failed policy_name is the user-specified name of the policy that threw the fault. BasicAuthentication.BA-Authenticate.failed = true

Example error response

{  
   "fault":{  
      "detail":{  
         "errorcode":"steps.basicauthentication.UnresolvedVariable"
      },
      "faultstring":"Unresolved variable : request.queryparam.password"
   }
}

Example fault rule

<FaultRule name="Basic Authentication Faults">
    <Step>
        <Name>AM-UnresolvedVariable</Name>
        <Condition>(fault.name Matches "UnresolvedVariable") </Condition>
    </Step>
    <Step>
        <Name>AM-AuthFailedResponse</Name>
        <Condition>(fault.name = "InvalidBasicAuthenticationSource")</Condition>
    </Step>
    <Condition>(BasicAuthentication.BA-Authentication.failed = true) </Condition>
</FaultRule>

MissingAtTargetEndpoint		 Concurrent Ratelimit policy {0} attachment is missing at target request/response/fault paths. This policy must be placed in the Target Request Preflow, Target Response Postflow, and DefaultFaultRule.
InvalidTTLForMessageTimeOut ConcurrentRatelimit invalid ttl value specified for message timeout. It must be a positive integer.

Fault variables

These variables are set when this policy triggers an error. For more information, see What you need to know about policy errors.

Variables Where Example
fault.name="fault_name" fault_name is the name of the fault, as listed in the Runtime errors table above. The fault name is the last part of the fault code. fault.name Matches "ConcurrentRatelimtViolation"

Note: The Error code shown in the example is correct, although it contains a misspelling ("limt"). Please be sure to use the code exactly as shown here when creating fault rules to trap this error.

concurrentratelimit.policy_name.failed policy_name is the user-specified name of the policy that threw the fault. concurrentratelimit.CRL-RateLimitPolicy.failed = true

Example error response

If the rate limit is exceeded, the policy returns only an HTTP status 503 to the client.

Example fault rule

<faultrule name="VariableOfNonMsgType"></faultrule><FaultRules>
    <FaultRule name="Quota Errors">
        <Step>

This section describes the fault codes and error messages that are returned and fault variables that are set by Edge when this policy triggers an error. This information is important to know if you are developing fault rules to handle faults. To learn more, see What you need to know about policy errors and Handling faults.

Runtime errors

These errors can occur when the policy executes.

Fault code HTTP status Cause Fix
steps.jsontoxml.ExecutionFailed 500 The input payload (JSON) is empty or the input (JSON) passed to JSON to XML policy is invalid or malformed.
steps.jsontoxml.InCompatibleTypes 500 This error occurs if the type of the variable defined in the <Source> element and the <OutputVariable> element are not the same. It is mandatory that the type of the variables contained within the <Source> element and the <OutputVariable> element matches. The valid types are message and string.
steps.jsontoxml.InvalidSourceType 500 This error occurs if the type of the variable used to define the <Source> element is invalid. The valid types of variable are message and string.
steps.jsontoxml.OutputVariableIsNotAvailable 500 This error occurs if the variable specified in the <Source> element of the JSON to XML Policy is of type string and the <OutputVariable> element is not defined. The <OutputVariable> element is mandatory when the variable defined in the <Source> element is of type string.
steps.jsontoxml.SourceUnavailable 500 This error occurs if the message variable specified in the <Source> element of the JSON to XML policy is either:
  • out of scope (not available in the specific flow where the policy is being executed) or
  • can't be resolved (is not defined)

Deployment errors

None.

Fault variables

These variables are set when a runtime error occurs. For more information, see What you need to know about policy errors.

Variables Where Example
fault.name="fault_name" fault_name is the name of the fault, as listed in the Runtime errors table above. The fault name is the last part of the fault code. fault.name Matches "SourceUnavailable"
jsontoxml.policy_name.failed policy_name is the user-specified name of the policy that threw the fault. jsontoxml.JSON-to-XML-1.failed = true

KeyValueMapOperations 政策

This section describes the fault codes and error messages that are returned and fault variables that are set by Edge when this policy triggers an error. This information is important to know if you are developing fault rules to handle faults. To learn more, see What you need to know about policy errors and Handling faults.

Runtime errors

These errors can occur when the policy executes.

Fault code HTTP status Cause Fix
steps.keyvaluemapoperations.SetVariableFailed 500

This error occurs if you try to retrieve a value from an encrypted key value map and set the value to a variable whose name does not have the prefix private. The prefix, which is required for basic security purposes during debugging, hides the encrypted values from API proxy Trace and debug sessions.
steps.keyvaluemapoperations.UnsupportedOperationException 500

This error occurs if the mapIdentifier attribute is set to empty string in the Key Value Map Operations policy.

Deployment errors

These errors can occur when you deploy a proxy containing this policy.

Error name Cause Fix
InvalidIndex If the index attribute specified in the <Get> element of Key Value Map Operations policy is zero or a negative number, then the deployment of the API proxy fails. The index starts from 1, so an index of zero or negative integer is considered as invalid.
KeyIsMissing This error occurs if the <Key> element is completely missing or <Parameter> element is missing within <Key> element underneath the <Entry> of the <InitialEntries> element of the Key Value Map Operations policy.
ValueIsMissing This error occurs if the <Value> element is missing underneath the <Entry> element of the <InitialEntries> element of the Key Value Map Operations policy.

PythonScript 政策

This section describes the fault codes and error messages that are returned and fault variables that are set by Edge when this policy triggers an error. This information is important to know if you are developing fault rules to handle faults. To learn more, see What you need to know about policy errors and Handling faults.

Runtime errors

These errors can occur when the policy executes.

Fault code HTTP status Cause Fix
steps.script.ScriptEvaluationFailed 500 The PythonScript policy can throw several different types of ScriptExecutionFailed errors. Commonly seen types of errors include NameError and ZeroDivisionError.

Deployment errors

These errors can occur when you deploy a proxy containing this policy.

Error name Cause Fix
InvalidResourceUrlFormat If the format of the resource URL specified within the <ResourceURL> or the <IncludeURL> element of the PythonScript policy is invalid, then the deployment of the API proxy fails.
InvalidResourceUrlReference If the <ResourceURL> or the <IncludeURL> elements refer to a PythonScript file that does not exist, then the deployment of the API proxy fails. The referenced source file must exist either the API proxy, environment, or organization level.

Fault variables

These variables are set when this policy triggers an error at runtime. For more information, see What you need to know about policy errors.

Variables Where Example
fault.name="fault_name" fault_name is the name of the fault, as listed in the Runtime errors table above. The fault name is the last part of the fault code. fault.name Matches "ScriptExecutionFailed"
pythonscript.policy_name.failed policy_name is the user-specified name of the policy that threw the fault. pythonscript.PythonScript-1.failed = true

部署錯誤

錯誤名稱 原因 修正
InvalidQuotaInterval 如未在 <Interval> 元素中指定的配額間隔 整數，則 API Proxy 的部署作業將會失敗。舉例來說 在 <Interval> 元素中指定的是 0.1，那麼 API Proxy 故障。
InvalidQuotaTimeUnit 如果 <TimeUnit> 元素中指定的時間單位不受支援， 那麼 API Proxy 的部署作業就會失敗支援的時間單位為 minute。 hour、day、week和month。
InvalidQuotaType 如果 <Quota> 中 type 屬性指定的配額類型 元素無效，即可部署 API Proxy。 支援的配額類型為 default、calendar、flexi 和 rollingwindow。
InvalidStartTime 如果 <StartTime> 元素中指定的時間格式是 無效，API Proxy 的部署作業就會失敗。有效格式為 yyyy-MM-dd HH:mm:ss。 採用 ISO 8601 日期和時間格式。適用對象 舉例來說，如果 <StartTime> 元素中指定的時間為 7-16-2017 12:00:00，則 API Proxy 的部署作業失敗。
StartTimeNotSupported 如果指定 <StartTime> 元素的配額類型並非 calendar 類型，即表示 API Proxy 的部署作業失敗。<StartTime> 元素是 僅支援「calendar」配額類型。舉例來說，如果設定 type 屬性 設為 flexi 或 rolling window，然後<Quota> API Proxy 部署作業失敗。
InvalidTimeUnitForDistributedQuota 如果 <Distributed> 元素設為 true，且 <TimeUnit> 元素設為 second，則 API Proxy 的部署作業會失敗。「second」的時間單位無效 分散式配額
InvalidSynchronizeIntervalForAsyncConfiguration 如果<SyncIntervalInSeconds> 配額政策中的 <AsynchronousConfiguration> 元素小於 0， API Proxy 部署作業失敗。
InvalidAsynchronizeConfigurationForSynchronousQuota 如果在配額政策中將 <AsynchronousConfiguration> 元素的值設為 true， 已使用 <AsynchronousConfiguration> 元素定義非同步設定，然後 API Proxy 部署作業失敗

This section describes the fault codes and error messages that are returned and fault variables that are set by Edge when this policy triggers an error. This information is important to know if you are developing fault rules to handle faults. To learn more, see What you need to know about policy errors and Handling faults.

Runtime errors

These errors can occur when the policy executes.

Fault code HTTP status Cause Fix
steps.messagevalidation.SourceMessageNotAvailable 500

This error occurs if a variable specified in the <Source> element of the policy is either:

  • out of scope (not available in the specific flow where the policy is being executed)
    • or
  • can't be resolved (is not defined)
steps.messagevalidation.NonMessageVariable 500

This error occurs if the <Source> element in the SOAPMessageValidation policy is set to a variable which is not of type message.

Message type variables represent entire HTTP requests and responses. The built-in Edge flow variables request, response, and message are of type message. To learn more about message variables, see the Variables reference.
steps.messagevalidation.Failed 500 This error occurs if the SOAPMessageValidation policy fails to validate the input message payload against the XSD schema or WSDL definition. It will also occur if there is malformed JSON or XML in the payload message.

Deployment errors

These errors can occur when you deploy a proxy containing this policy.

Error name Cause Fix
InvalidResourceType The <ResourceURL> element in the SOAPMessageValidation policy is set to a resource type not supported by the policy.
ResourceCompileFailed The resource script referenced in the <ResourceURL> element of the SOAPMessageValidation policy contains an error that prevents it from compiling.
RootElementNameUnspecified The <Element> element in the SOAPMessageValidation policy does not contain the root element's name.

These errors can occur when you deploy a proxy containing this policy.

Error name Cause Fix
SourceNotConfigured One or more of the following elements of the Validate SAML Assertion policy is not defined or empty: <Source>, <XPath>, <Namespaces>, <Namespace>.
TrustStoreNotConfigured If the <TrustStore> element is empty or not specified in the ValidateSAMLAssertion policy, then the deployment of the API proxy fails. A valid Trust Store is required.
NullKeyStoreAlias If the child element <Alias> is empty or not specified in the <Keystore> element of Generate SAML Assertion policy, then the deployment of the API proxy fails. A valid Keystore alias is required.
NullKeyStore If the child element <Name> is empty or not specified in the <Keystore> element of GenerateSAMLAssertion policy, then the deployment of the API proxy fails. A valid Keystore name is required.
NullIssuer If the <Issuer> element is empty or not specified in the Generate SAML Assertion policy, then the deployment of the API proxy fails. A valid <Issuer> value is required.

Fault variables

These variables are set when a runtime error occurs. For more information, see What you need to know about policy errors.

Variables Where Example
fault.name="fault_name" fault_name is the name of the fault. The fault name is the last part of the fault code. fault.name = "InvalidMediaTpe"
GenerateSAMLAssertion.failed For a validate SAML assertion policy configuration, the error prefix is ValidateSAMLAssertion. GenerateSAMLAssertion.failed = true

Example error response

{
  "fault": {
    "faultstring": "GenerateSAMLAssertion[GenSAMLAssert]: Invalid media type",
    "detail": {
      "errorcode": "steps.saml.generate.InvalidMediaTpe"

XMLThreatProtection 政策

This section describes the fault codes and error messages that are returned and fault variables that are set by Edge when this policy triggers an error. This information is important to know if you are developing fault rules to handle faults. To learn more, see What you need to know about policy errors and Handling faults.

Runtime errors

These errors can occur when the policy executes.

Fault code HTTP status Cause Fix
steps.xmlthreatprotection.ExecutionFailed 500 The XMLThreatProtection policy can throw many different types of ExecutionFailed errors. Most of these errors occur when a specific threshold set in the policy is exceeded. These types of errors include: element name length, child count, node depth, attribute count, attribute name length, and many others. You can see the complete list in the XMLThreatProtection policy runtime error troubleshooting topic.
steps.xmlthreatprotection.InvalidXMLPayload 500 This error occurs if the input message payload specified by the XMLThreatProtection policy's <Source> element is not a valid XML Document.
steps.xmlthreatprotection.SourceUnavailable 500 This error occurs if the message variable specified in the <Source> element is either:
  • Out of scope (not available in the specific flow where the policy is being executed)
  • Is not one of the valid values request, response, or message
steps.xmlthreatprotection.NonMessageVariable 500 This error occurs if the <Source> element is set to a variable which is not of type message.

Notes:

  • The error name ExecutionFailed is the default error name and will be returned regardless of the type of error detected; however, this default can be changed by setting an organization-level property. When this property is set, the error name will reflect the actual error. For example, "TextExceeded" or "AttrValueExceeded". See Usage Notes for details.
  • The 500 HTTP status is the default; however, the HTTP Status can be changed to 400 for request flow faults by setting an organization-level property. See Usage Notes for details.

Deployment errors

None.

Fault variables

These variables are set when a runtime error occurs. For more information, see What you need to know about policy errors.

Variables Where Example
fault.name="fault_name" fault_name is the name of the fault, as listed in the Runtime errors table above. The fault name is the last part of the fault code. fault.name Matches "SourceUnavailable"
xmlattack.policy_name.failed policy_name is the user-specified name of the policy that threw the fault. xmlattack.XPT-SecureRequest.failed = true

Example error response

{
  "fault": {
    "faultstring": "XMLThreatProtection[XPT-SecureRequest]: Execution failed. reason: XMLThreatProtection[XTP-SecureRequest]: Exceeded object entry name length at line 2",
    "detail": {
      "errorcode": "steps.xmlthreatprotection.ExecutionFailed"
    }
  }
}

Example fault rule

<FaultRule name="XML Threat Protection Policy Faults">
    <Step>
        <Name>AM-CustomErrorResponse</Name>
        <Condition>(fault.name Matches "ExecutionFailed") </Condition>
    </Step>
    <Condition>(xmlattack.XPT-SecureRequest.failed = true) </Condition>
</FaultRule>

執行階段錯誤

執行政策時，可能會發生這些錯誤。

錯誤程式碼 HTTP 狀態 原因 修正
steps.xmltojson.ExecutionFailed 500 如果輸入酬載 (XML) 為空白，或是輸入的 XML 無效或格式錯誤，就會出現這個錯誤。
steps.xmltojson.InCompatibleType 500 如果 <Source> 元素中定義的變數類型與 <OutputVariable> 元素不同。你必須將變數類型設為 包含在 <Source> 元素中，且 <OutputVariable> 元素相符。
steps.xmltojson.InvalidSourceType 500 如果用來定義 <Source> 元素的變數類型為 無效。有效的變數類型為訊息和字串。
steps.xmltojson.OutputVariableIsNotAvailable 500 如果 XML 的 <Source> 元素中指定的變數為 JSON 政策的類型為字串，且未定義 <OutputVariable> 元素。 如果在 <Source> 中定義的變數，則 <OutputVariable> 是必要元素 元素屬於類型字串。
steps.xmltojson.SourceUnavailable 500 如果系統傳回這個錯誤，表示 message 而 XML 到 JSON 政策的 <Source> 元素中指定的是以下任一變數：
  • 超出範圍 (不適用於執行政策的特定流程)
  • 無法解析 (未定義)

部署錯誤

當您部署含有這項政策的 Proxy 時，可能會發生這些錯誤。

錯誤名稱 原因 修正
EitherOptionOrFormat 如果不是 <Options> 或 <Format> 元素 在 XML 政策中宣告為 JSON 政策，則 API Proxy 的部署會失敗。
UnknownFormat 如果 XML 到 JSON 政策中的 <Format> 元素有不明值 格式定義，API Proxy 的部署作業就會失敗。預先定義的格式包括： xml.com、yahoo、google和badgerFish。

XSLTransform 政策

Runtime errors

These errors can occur when the policy executes.

Fault code HTTP status Cause Fix
steps.xsl.XSLSourceMessageNotAvailable 500 This error occurs if the message or string variable specified in the <Source> element of the XSL Transform policy is either out of scope (not available in the specific flow where the policy is being executed) or can't be resolved (is not defined).
steps.xsl.XSLEvaluationFailed 500 This error occurs if the input XML payload is unavailable/malformed or the XSLTransform policy fails/is unable to transform the input XML file based on the transformation rules provided in the XSL file. There could be many different causes for the XSLTransform policy to fail. The reason for failure in the error message will provide more information on the cause.

Deployment errors

These errors can occur when you deploy a proxy containing this policy.

Error name Cause Fix
XSLEmptyResourceUrl If the <ResourceURL> element in the XSL Transform policy is empty, then the deployment of the API proxy fails.
XSLInvalidResourceType If the resource type specified in the <ResourceURL> element of the XSL Transform policy is not of type xsl, then the deployment of the API proxy fails.
