FastAPI unterstützt (und empfiehlt die Verwendung von) `Annotated` seit Version 0.95.0.

Wenn Sie eine ältere Version haben, werden Sie Fehler angezeigt bekommen, wenn Sie versuchen, `Annotated` zu verwenden.

Bitte [aktualisieren Sie FastAPI](../../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} daher mindestens zu Version 0.95.1, bevor Sie `Annotated` verwenden.
