Before going further, a few points need to be more clear. Can you provide the request’s payload you’re sending ? What’s the exact response message or the traceback ? Can you print a serializer’s (not your code, but an actual serializer’s instance) so we can check what constraints it has ? Did you try with the latest Django REST framework version ?
