Fault codes

This page applies to Apigeeand Apigee hybrid.

Apigee provides a set of fault codes for various features that help you to diagnose issues. For example, a typical 4xx or 5xx HTTP status code can be classified using one or more fault codes.

Fault codes provide you with useful information about runtime errors, including information about the source and name of the error in the following format: [prefix].[error_name]

For example: steps.raisefault.RaiseFault

In this example:

• steps.raisefault is the prefix that indicates the RaiseFault policy generated the error.

• RaiseFault is the error name that helps you determine the cause of the error. In this case, more information would be provided by the fault string.

  • For policy errors, error-specific flow variables are populated that are useful for fault handling. See What you need to know about policy errors .
  • When setting up alerts , fault codes are organized by category and subcategory, and display the human-readable name. When using the Investigate dashboard, the raw fault codes are displayed.

The following table summarizes the fault codes, organized by category and sub-category.
