Hi devs, Now the API spits error messages irrespective of the backend exception. It sends the JSON error message even if there is an Nullpointer in our backend. Writing a exception mapper for throwable did the trick.
Here is the schema I came up with for validating input. I derived it from the sample inputs i have. Please review it. Pretty sure there is space for improvements particularly min occurs. <?xml version="1.0" encoding="UTF-8" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";> <xs:element name="partition">
