If an exception occurs, the`Request` instance will still be in scope, so we can read and make use of the request body when handling the error:

```Python hl_lines="16-18"

```

## Custom `APIRoute` class in a router

You can also set the `route_class` parameter of an `APIRouter`:

{!../../../docs_src/custom_request_and_route/tutorial002.py!}
```

Wenn eine Exception auftritt, befindet sich die `Request`-Instanz weiterhin im Gültigkeitsbereich, sodass wir den Requestbody lesen und bei der Fehlerbehandlung verwenden können:

```Python hl_lines="16-18"
{!../../../docs_src/custom_request_and_route/tutorial002.py!}
```
