## Zusammenfassung { #summary }

     *
     * Unfortunately, we don't distinguish between these two cases in our public API: Joiner.on(...)
     * and Joiner.on(...).useForNull(...) both declare the same return type: plain Joiner. To ensure
     * that users *can* pass null arguments to Joiner, we annotate it as if it always tolerates null
     * inputs, rather than as if it never tolerates them.

쿼리 매개변수 `tool`이 허용되지 않는다는 **에러** 응답을 받게 됩니다:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["query", "tool"],

            "input": "plumbus"
        }
    ]
}
```

**FastAPI**에서 **쿼리 매개변수**를 선언할 때 **Pydantic 모델**을 사용할 수 있습니다. 😎
