Wenn Sie eine `HTTPException` auslösen, können Sie dem Parameter `detail` jeden Wert übergeben, der in JSON konvertiert werden kann, nicht nur `str`.

Sie könnten ein `dict`, eine `list`, usw. übergeben.

/// tip | Astuce

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

Vous pouvez passer un `dict`, une `list`, etc.
