Prefer to use the `Annotated` version if possible.

////

/// info

FastAPI added support for `Annotated` (and started recommending it) in version 0.95.0.

If you have an older version, you would get errors when trying to use `Annotated`.

### Gerar o esquema OpenAPI

Em seguida, use a mesma função utilitária para gerar o esquema OpenAPI, dentro de uma função `custom_openapi()`:

```Python hl_lines="2  15-21"
{!../../docs_src/extending_openapi/tutorial001.py!}
```

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