## Corrotinas

Si vous avez une version plus ancienne, vous obtiendrez des erreurs en essayant d'utiliser `Annotated`.

Assurez-vous de [Mettre à jour la version de FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} à la version 0.95.1 à minima avant d'utiliser `Annotated`.
