Aber der Client/Benutzer sieht ihn nicht. Stattdessen erhält der Client einen <abbr title="Interner Server-Fehler">„Internal Server Error“</abbr> mit einem HTTP-Statuscode `500`.

Das ist, wie es sein sollte, denn wenn Sie einen Pydantic-`ValidationError` in Ihrer *Response* oder irgendwo sonst in ihrem Code haben (es sei denn, im *Request* des Clients), ist das tatsächlich ein Bug in ihrem Code.

* **`400`** 以上は「クライアントエラー」のレスポンスのためのものです。これらは、おそらく最も多用するであろう２番目のタイプです。
    * 例えば、`404`は「Not Found」レスポンスです。
    * クライアントからの一般的なエラーについては、`400`を使用することができます。
* `500`以上はサーバーエラーのためのものです。これらを直接使うことはほとんどありません。アプリケーションコードやサーバーのどこかで何か問題が発生した場合、これらのステータスコードのいずれかが自動的に返されます。

                    valid, that would mean a violation of the contract with the client,
                    so it's an error from the API developer. So, FastAPI will raise an
                    error and return a 500 error code (Internal Server Error).

                Read more about it in the
                [FastAPI docs for Response Model](https://fastapi.tiangolo.com/tutorial/response-model/).

 * second. This could be accomplished by requiring a permit per byte, and specifying a rate of 5000
 * permits per second:
 *
 * <pre>{@code
 * final RateLimiter rateLimiter = RateLimiter.create(5000.0); // rate = 5000 permits per second
