Improving Error Responses of APIM RESTful APIs

[rmsamitha]

Problem

Some of the scenarios in REST APIs are returning incorrect HTTP status codes and error descriptions, often resulting in a 500 - Internal Server Error, which misleads API developers who apply changes to the APIs using the RESTful approach. This is observed much when an incorrect payload is passed to the rest api. So the response error codes should be 400 instead of 500. And proper error description should be returned as well.
