Hi there, I got some format issue on json respone. I would like to give some error message on my controller. below is my code and it is sending 400 response but I tried with Postman and there is no specific message.

if citizen_chk != True:
       return Response(json.dumps({"err":"Login only for citizen"}),content_type='application/json;charset=utf-8',status=400)

I got the response in postman as below,

{"jsonrpc": "2.0", "id": null, "result": " Response 53 bytes [400 BAD REQUEST] "}

May I know how to show my message " Login only for citizen" ?

Thanks
