Para resolver este mismo problema, probablemente sea mucho más fácil usar el `body` en un manejador personalizado para `RequestValidationError` ([Manejo de Errores](../tutorial/handling-errors.md#use-the-requestvalidationerror-body){.internal-link target=_blank}).

Pero este ejemplo sigue siendo válido y muestra cómo interactuar con los componentes internos.
