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>

基本身份验证政策

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">

ExtractVariables 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.extractvariables.ExecutionFailed 500

This error occurs when:

  • The input payload (JSON, XML) is empty.
  • The input (JSON, XML, etc) passed to the policy is invalid or malformed.
steps.extractvariables.ImmutableVariable 500 A variable used in the policy is immutable. The policy was unable to set this variable.
steps.extractvariables.InvalidJSONPath 500 This error occurs if an invalid JSON path is used in the JSONPath element of the policy. For example, if a JSON payload does not have the object Name, but you specify Name as the path in the policy, then this error occurs.
steps.extractvariables.JsonPathParsingFailure 500 This error occurs when the policy is unable to parse a JSON path and extract data from the flow variable specified in Source element. Typically this happens if the flow variable specified in the Source element does not exist in the current flow.
steps.extractvariables.SetVariableFailed 500 This error occurs if the policy could not set the value to a variable. The error generally happens if you try to assign values to multiple variables whose names start with the same words in a nested dot-separated format.
steps.extractvariables.SourceMessageNotAvailable 500 This error occurs if the message 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.extractvariables.UnableToCast 500 This error occurs if the policy was unable to cast the extracted value to a variable. Typically this happens if you attempt to set the value of one data type to a variable of another data type.

Deployment errors

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

Error name Cause Fix
NothingToExtract If the policy does not have any of the elements URIPath, QueryParam, Header, FormParam, XMLPayload, or JSONPayload, the deployment of the API Proxy fails, because there's nothing to extract.
NONEmptyPrefixMappedToEmptyURI This error occurs if the policy has a prefix defined in the Namespace element under the XMLPayload element, but no URI is defined.
DuplicatePrefix This error occurs if the policy has the same prefix defined more than once in the Namespace element under the XMLPayload element.
NoXPathsToEvaluate If the policy does not have the XPath element within the XMLPayload element, then the deployment of the API proxy fails with this error.
EmptyXPathExpression If the policy has an empty XPath expression within the XMLPayload element, then the deployment of the API proxy fails.
NoJSONPathsToEvaluate If the policy does not have the JSONPath element within the JSONPayload element, then the deployment of the API proxy fails with this error.
EmptyJSONPathExpression If the policy has an empty XPath expression within the XMLPayload element, then the deployment of the API proxy fails.
MissingName If the policy does not have the name attribute in any of the policy elements like QueryParam, Header, FormParam or Variable, where it is required, then the deployment of the API proxy fails.
PatternWithoutVariable If the policy does not have a variable specified within the Pattern element, then the deployment of the API proxy fails. The Pattern element requires the name of the variable in which extracted data will be stored.
CannotBeConvertedToNodeset If the policy has an XPath expression where the Variable type is defined as nodeset, but the expression cannot be converted to nodeset, then the deployment of the API proxy fails.
JSONPathCompilationFailed The policy could not compile a specified JSON Path.
InstantiationFailed The policy could not be instantiated.
XPathCompilationFailed If the prefix or the value used in the XPath element is not part of any of the declared namespaces in the policy, then the deployment of the API proxy fails.
InvalidPattern If the Pattern element definition is invalid in any of the elements like URIPath, QueryParam, Header, FormParam, XMLPayload or JSONPayload within the policy, then the deployment of the API proxy fails.

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 = "SourceMessageNotAvailable"
extractvariables.policy_name.failed policy_name is the user-specified name of the policy that threw the fault. extractvariables.EV-ParseJsonResponse.failed = true

Example error response

{
   "fault":{
      "detail":{
         "errorcode":"steps.extractvariables.SourceMessageNotAvailable"
      },
      "faultstring":"request message is not available for ExtractVariable: EV-ParseJsonResponse"
   }
}

Example fault rule

JavaScript 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.javascript.ScriptExecutionFailed 500 The JavaScript policy can throw many different types of ScriptExecutionFailed errors. Commonly seen types of errors include RangeError, ReferenceError, SyntaxError, TypeError, and URIError.
steps.javascript.ScriptExecutionFailedLineNumber 500 An error occurred in the JavaScript code. See the fault string for details. N/A
steps.javascript.ScriptSecurityError 500 A security error occurred when the JavaScript executed. See the fault string for details. N/A

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 JavaScript policy is invalid, then the deployment of the API proxy fails.
InvalidResourceUrlReference If the <ResourceURL> or the <IncludeURL> elements refer to a JavaScript 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.
WrongResourceType This error occurs during deployment if the <ResourceURL> or the <IncludeURL> elements of the JavaScript policy refer to any resource type other than jsc (JavaScript file).
NoResourceURLOrSource The deployment of the JavaScript policy can fail with this error if the <ResourceURL> element is not declared or if the resource URL is not defined within this element. <ResourceURL> element is a mandatory element. Or, The <IncludeURL> element is declared but the resource URL is not defined within this element. The <IncludeURL> element is optional but if declared, the resource URL must be specified within the <IncludeURL> element.

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"
javascript.policy_name.failed policy_name is the user-specified name of the policy that threw the fault. javascript.JavaScript-1.failed = true

Example error response

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.

keymanagement.service.invalid_client-app_not_approved 401 与 API 密钥关联的开发者应用已被撤消。撤消的应用无法访问任何 API 产品，也无法调用由 Apigee Edge 管理的任何 API。组织管理员可以使用管理 API 更改开发者应用的状态。请参阅批准或撤消开发者应用。
oauth.v2.FailedToResolveAPIKey 401 该政策要求在政策的 <APIKey> 元素中指定的变量中找到 API 密钥。 当预期变量不存在（无法解析）时，会发生此错误。
oauth.v2.InvalidApiKey 401 Edge 已收到 API 密钥，但该密钥无效。当 Edge 在其数据库中查找密钥时，它必须与请求中发送的密钥完全匹配。如果 API 之前有效，请确保未重新生成密钥。如果重新生成密钥，且您尝试使用旧密钥，则会看到此错误。如需了解详情，请参阅注册应用和管理 API 密钥。
oauth.v2.InvalidApiKeyForGivenResource 401 Edge 已收到 API 密钥，且该密钥有效；但是，它与通过产品与 API 代理关联的开发者应用中的已批准密钥不匹配。

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 "TokenExpired"
JWS.failed All JWS policies set the same variable in the case of a failure. jws.JWS-Policy.failed = true

Example error response

For error handling, the best practice is to trap the errorcode part of the error response. Do not rely on the text in the faultstring, because it could change.

Example fault rule

<FaultRules>
    <FaultRule name="JWS Policy Errors">
        <Step>
            <Name>JavaScript-1</Name>
            <Condition>(fault.name Matches "TokenExpired")</Condition>
