Policy error reference

Access Control policy

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.accesscontrol.IPDeniedAccess 403 The client IP address, or an IP address passed as part of the X-Forwarded-For HTTP header in the API request, matches an IP address specified in the <SourceAddress> element within the <MatchRule> element of the Access Control Policy, and the action attribute of the <MatchRule> element is set to DENY. build

Fault variables

These variables are set when a runtime error occurs. For more information, see Variables specific to 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 "IPDeniedAccess"
acl.policy_name.failed policy_name is the user-specified name of the policy that threw the fault. acl.AC-AllowAccess.failed = true

Example fault response

{
   "fault":{
      "detail":{
         "errorcode":"steps.accesscontrol.IPDeniedAccess"
      },
      "faultstring":"Access Denied for client ip : 52.211.243.3"
   }
}

Example fault rule

<FaultRule name="IPDeniedAccess">
    <Step>
        <Name>AM-IPDeniedAccess</Name>
        <Condition>(fault.name Matches "IPDeniedAccess") </Condition>
    </Step>
    <Condition>(acl.failed = true) </Condition>
</FaultRule>

Access Entity policy

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.

Assign Message policy

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.

build
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)
build

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. build
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. build
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"

NONEmptyPrefixMappedToEmptyURI This error occurs if the policy has a prefix defined in the Namespace element under the XMLPayload element, but no URI is defined. build
DuplicatePrefix This error occurs if the policy has the same prefix defined more than once in the Namespace element under the XMLPayload element. build
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. build
EmptyXPathExpression If the policy has an empty XPath expression within the XMLPayload element, then the deployment of the API proxy fails. build
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. build
EmptyJSONPathExpression If the policy has an empty XPath expression within the XMLPayload element, then the deployment of the API proxy fails. build
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. build
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. build
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. build
JSONPathCompilationFailed The policy could not compile a specified JSON Path.

ValidateToken
InvalidateToken

steps.oauth.v2.InsufficientScope 403 The access token presented in the request has a scope that does not match the scope specified in the verify access token policy. To learn about scope, see Working with OAuth2 scopes. VerifyAccessToken
steps.oauth.v2.invalid_access_token 401 The access token sent from the client is invalid. VerifyAccessToken
steps.oauth.v2.invalid_client 401

This error name is returned when the <GenerateResponse> property of the policy is set to true and the client ID sent in the request is invalid. Check to be sure you are using the correct client key and secret values for the Developer App associated with your proxy. Typically, these values are sent as a Base64 encoded Basic Authorization header.

Note: It is recommended that you change existing fault rule conditions to catch both the invalid_client and InvalidClientIdentifier names. See the 16.09.21 Release Notes for more information and an example.

GenerateAccessToken
RefreshAccessToken
steps.oauth.v2.invalid_request 400 This error name is used for multiple different kinds of errors, typically for missing or incorrect parameters sent in the request. If <GenerateResponse> is set to false, use fault variables (described below) to retrieve details about the error, such as the fault name and cause. GenerateAccessToken
GenerateAuthorizationCode
GenerateAccessTokenImplicitGrant
RefreshAccessToken
steps.oauth.v2.InvalidAccessToken 401 The authorization header does not have the word "Bearer", which is required. For example: Authorization: Bearer your_access_token VerifyAccessToken
steps.oauth.v2.InvalidAPICallAsNo\
steps.oauth.v2.ApiProductMatchFound
401

The API proxy is not in the Product associated with the access token.

Tips: Be sure that the product associated with the access token is configured correctly. For example, if you use wildcards in resource paths, be sure the wildcards are being used correctly. See Create API products for details.

See also this Apigee Community post for more guidance on causes for this error.

VerifyAccessToken
steps.oauth.v2.InvalidClientIdentifier 500

This error name is returned when the <GenerateResponse> property of the policy is set to false and the client ID sent in the request is invalid. Check to be sure you are using the correct client key and secret values for the Developer App associated with your proxy. Typically, these values are sent as a Base64 encoded Basic Authorization header.

Note: In this situation, this error used to be called invalid_client. It is recommended that you change existing fault rule conditions to catch both the invalid_client and InvalidClientIdentifier names. See the 16.09.21 Release Notes for more information and an example.

GenerateAccessToken
RefreshAccessToken

steps.oauth.v2.InvalidParameter 500 The policy must specify either an access token or an authorization code, but not both. GenerateAuthorizationCode
GenerateAccessTokenImplicitGrant
steps.oauth.v2.InvalidTokenType 500 The <Tokens>/<Token> element requires you to specify the token type (for example, refreshtoken). If the client passes the wrong type, this error is thrown. ValidateToken
InvalidateToken
steps.oauth.v2.MissingParameter 500 The response type is token, but no grant types are specified. GenerateAuthorizationCode
GenerateAccessTokenImplicitGrant
steps.oauth.v2.UnSupportedGrantType 500

The client specified a grant type that is unsupported by the policy (not listed in the <SupportedGrantTypes> element).

Note: There is currently a bug where unsupported grant type errors are not thrown correctly. If an unsupported grant type error occurs, the proxy does not enter the Error Flow, as expected.

keymanagement.service.invalid_client-app_not_approved 401 The Developer App associated with the API key is revoked. A revoked app cannot access any API products and cannot invoke any API managed by Apigee Edge. An org admin can change the status of a Developer App using the management API. See Approve or Revoke Developer App.
oauth.v2.FailedToResolveAPIKey 401 The policy expects to find the API key in a variable that is specified in the policy's <APIKey> element. This error arises when the expected variable does not exist (it cannot be resolved).
oauth.v2.InvalidApiKey 401 An API key was received by Edge, but it is invalid. When Edge looks up the key in its database, it must exactly match the on that was sent in the request. If the API worked previously, make sure the key was not regenerated. If the key was regenerated, you will see this error if you try to use the old key. For details, see Register apps and manage API keys.
oauth.v2.InvalidApiKeyForGivenResource 401 An API key was received by Edge, and it is valid; however, it does not match an approved key in the Developer App associated with your API proxy through a Product.

Deployment errors

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

Error name Cause
SpecifyValueOrRefApiKey The <APIKey> element does not have a value or key specified.

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 "FailedToResolveAPIKey"
oauthV2.policy_name.failed policy_name is the user-specified name of the policy that threw the fault. oauthV2.VK-VerifyAPIKey.failed = true

Example error responses

{  
   "fault":{  
      "faultstring":"Invalid ApiKey",
      "detail":{  
         "errorcode":"oauth.v2.InvalidApiKey"
      }
   }
}
{  
   "fault":{  
      "detail":{  
         "errorcode":"keymanagement.service.DeveloperStatusNotActive"
      },
      "faultstring":"Developer Status is not Active"
   }
}

Example fault rule

<FaultRule name="FailedToResolveAPIKey">
    <Step>
        <Name>AM-FailedToResolveAPIKey</Name>
    </Step>
    <Condition>(fault.name Matches "FailedToResolveAPIKey") </Condition>

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>

XML Threat Protection policy

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. build
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. build
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
build
steps.xmlthreatprotection.NonMessageVariable 500 This error occurs if the <Source> element is set to a variable which is not of type message. build

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
