## Accessing the request body in an exception handler !!! tip To solve this same problem, it's probably a lot easier to use the `body` in a custom handler for `RequestValidationError` ([Handling Errors](../tutorial/handling-errors.md#use-the-requestvalidationerror-body){.internal-link target=_blank}).

À la place, en étant "asynchrone", une fois terminée, une tâche peut légèrement attendre (quelques microsecondes) que l'ordinateur / le programme finisse ce qu'il était en train de faire, et revienne récupérer le résultat.

When a request contains invalid data, **FastAPI** internally raises a `RequestValidationError`. And it also includes a default exception handler for it. To override it, import the `RequestValidationError` and use it with `@app.exception_handler(RequestValidationError)` to decorate the exception handler. The exception handler will receive a `Request` and the exception. ```Python hl_lines="2 14-16" {!../../../docs_src/handling_errors/tutorial004.py!}
