When returning a response with data, you can omit the status parameter name if you're using HTTP_200_OK.

return Response(serializer.data, status.HTTP_200_OK)

However, when returning a response without data, simply passing the status code without the parameter name won't work as expected.

return Response(status.HTTP_204_NO_CONTENT)

You must explicitly specify the status parameter name.

return Response(status=status.HTTP_204_NO_CONTENT)
