作为人类，我们总是会犯**错误**。 软件几乎*总是*在不同的地方隐藏着**bug**。 🐛

作为开发人员，当我们发现这些bug并实现新功能（也可能添加新bug😅）时，我们会不断改进代码。

### 自动处理小错误

使用 FastAPI 构建 Web API 时，如果我们的代码中存在错误，FastAPI 通常会将其包含到触发错误的单个请求中。 🛡

对于该请求，客户端将收到 **500 内部服务器错误**，但应用程序将继续处理下一个请求，而不是完全崩溃。

### 更大的错误 - 崩溃

尽管如此，在某些情况下，我们编写的一些代码可能会导致整个应用程序崩溃，从而导致 Uvicorn 和 Python 崩溃。 💥

尽管如此，您可能不希望应用程序因为某个地方出现错误而保持死机状态，您可能希望它**继续运行**，至少对于未破坏的*路径操作*。

### 崩溃后重新启动

**FastAPI** は`response_model`でPydanticモデルを使用していて、データにエラーがあった場合、ログにエラーが表示されるようにこれを使用しています。

しかし、クライアントやユーザーはそれを見ることはありません。その代わりに、クライアントはHTTPステータスコード`500`の「Internal Server Error」を受け取ります。

*レスポンス*やコードのどこか（クライアントの*リクエスト*ではなく）にPydanticの`ValidationError`がある場合、それは実際にはコードのバグなのでこのようにすべきです。

また、あなたがそれを修正している間は、セキュリティの脆弱性が露呈する場合があるため、クライアントやユーザーがエラーに関する内部情報にアクセスできないようにしてください。

## Changes since v1.3.0-alpha.3

### Action Required

* validate third party resources ([#25007](https://github.com/kubernetes/kubernetes/pull/25007), [@liggitt](https://github.com/liggitt))
* Automatically create the kube-system namespace ([#25196](https://github.com/kubernetes/kubernetes/pull/25196), [@luxas](https://github.com/luxas))
