Néanmoins, cela reste faisable dans **FastAPI**, via les outils internes de Starlette.

Et la documentation fonctionne quand même, bien qu'aucune section ne soit ajoutée pour dire que la paramètre devrait contenir un *chemin*.

### Convertisseur de *chemin*

The benefit of raising an exception over returning a value will be more evident in the section about Dependencies and Security.

In this example, when the client requests an item by an ID that doesn't exist, raise an exception with a status code of `404`:
