Server returns 500 when trying to DELETE a non-existing resource

DELETE is an idempotent method and therefore should always succeed. If resource is not there, return success, meaning it is still not there.

But today server returns internal server error

Example:

DELETE http://localhost:8080/restconf/config/service-function:service-functions/

HTTP Status 500 - Internal Server Error

type Status report

message Internal Server Error

description The server encountered an internal error that prevented it from fulfilling this request.
