A company wants to inform the consumers of their services whether the DataPower processing failed in the request or the response. They prefer to have generic error handling shared by all their rules and thus have not defined any on-error actions on individual rules. From the default error rule configured, the requirement is to inform the consumer whether the processing policy failed in the request or the response. What extension function should the solution implementer use to implement the requirement?
