Diese Handler kümmern sich darum, Default-JSON-Responses zurückzugeben, wenn Sie eine `HTTPException` `raise`n, und wenn der Request ungültige Daten enthält.

Sie können diese Exceptionhandler mit ihren eigenen überschreiben.

### Requestvalidierung-Exceptions überschreiben

Wenn ein Request ungültige Daten enthält, löst **FastAPI** intern einen `RequestValidationError` aus.

Und bietet auch einen Default-Exceptionhandler dafür.
