Policy error reference

This page applies to Apigee and Apigee hybrid.

View Apigee Edge documentation.

Every policy document includes an error reference section that describes the fault codes and error messages that are returned and fault variables that are set by Apigee when the policy triggers an error. The error reference section includes:

Runtime errors
Deployment errors
Fault variables
Examples

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.

For a current list of all policies, see Policy reference.

Refer to the individual policy documents for error codes specific to that policy. For example, see AssignMessage policy, Error codes.
