하지만 클라이언트가 `http://example.com/items/bar`(존재하지 않는 `item_id` `"bar"`)를 요청하면, HTTP 상태 코드 404("not found" 오류)와 다음 JSON 응답을 받습니다:

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

/// tip | 팁

`HTTPException`을 발생시킬 때 `detail` 파라미터로 `str`만 전달할 수 있는 것이 아니라, JSON으로 변환할 수 있는 어떤 값이든 전달할 수 있습니다.

`dict`, `list` 등을 전달할 수 있습니다.

이들은 **FastAPI**가 자동으로 처리해 JSON으로 변환합니다.
