Estos manejadores se encargan de devolver los responses JSON predeterminadas cuando lanzas un `HTTPException` y cuando el request tiene datos inválidos.

Puedes sobrescribir estos manejadores de excepciones con los tuyos propios.

### Sobrescribir excepciones de validación de request { #override-request-validation-exceptions }

Cuando un request contiene datos inválidos, **FastAPI** lanza internamente un `RequestValidationError`.

* Importa `Jinja2Templates`.
* Crea un objeto `templates` que puedas reutilizar más tarde.
* Declara un parámetro `Request` en la *path operation* que devolverá una plantilla.
* Usa los `templates` que creaste para renderizar y devolver un `TemplateResponse`, pasa el nombre de la plantilla, el objeto de request, y un diccionario "context" con pares clave-valor que se usarán dentro de la plantilla Jinja2.
