Cuando devuelves un `Response` directamente, como en el ejemplo anterior, se devuelve directamente.

No se serializará con un modelo, etc.

Asegúrate de que tenga los datos que deseas que tenga y que los valores sean JSON válidos (si estás usando `JSONResponse`).

También podrías usar `from starlette.responses import JSONResponse`.
