例如，若客戶端嘗試送出名為 `santa_tracker`、值為 `good-list-please` 的 Cookie，客戶端會收到**錯誤**回應，告知 `santa_tracker` 這個 <dfn title="聖誕老人不贊同沒有餅乾。🎅 好的，不再講餅乾笑話了。">Cookie 不被允許</dfn>：

```json
{
    "detail": [
        {

            "loc": ["cookie", "santa_tracker"],

        }
    ]
}
```

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

/// tip

When raising an `HTTPException`, you can pass any value that can be converted to JSON as the parameter `detail`, not only `str`.

You could pass a `dict`, a `list`, etc.

They are handled automatically by **FastAPI** and converted to JSON.
