Mais si le client demande `http://example.com/items/bar` (un `item_id` inexistant « bar »), il recevra un code d'état HTTP 404 (l'erreur « not found ») et une réponse JSON :

```JSON
{
  "detail": "Item not found"
}
```

/// tip | Astuce

Lorsque vous levez une `HTTPException`, vous pouvez passer n'importe quelle valeur convertible en JSON comme paramètre `detail`, pas uniquement un `str`.
