* **`400 - 499`** son para responses de "Error del Cliente". Este es el segundo tipo que probablemente más usarías.
    * Un ejemplo es `404`, para un response "Not Found".
    * Para errores genéricos del cliente, puedes usar simplemente `400`.

		if ok {

				// With newer config disallowing changing / turning off

```JSON
{
  "item": "The Foo Wrestlers"
}
```

しかし、クライアントが`http://example.com/items/bar`（存在しない`item_id` `"bar"`）をリクエストした場合、HTTPステータスコード404（"not found"エラー）と以下のJSONレスポンスが返されます:

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

/// tip | 豆知識

`HTTPException`を発生させる際には、`str`だけでなく、JSONに変換できる任意の値を`detail`パラメータとして渡すことができます。

`dict`や`list`などを渡すことができます。
