So, you will have to make sure your data is of the correct type. E.g. it is compatible with JSON, if you are returning a `JSONResponse`.

And also that you are not sending any data that should have been filtered by a `response_model`.

You could also use `from starlette.responses import Response` or `from starlette.responses import JSONResponse`.
