## 再起動 { #restarts }

起動時にアプリケーションが実行されることを確認するのと同様に、失敗後にアプリケーションが**再起動**されることも確認したいと思われます。

### 我々は間違いを犯す { #we-make-mistakes }

私たち人間は常に**間違い**を犯します。ソフトウェアには、ほとんど常に**バグ**があらゆる箇所に隠されています。🐛

そして私たち開発者は、それらのバグを見つけたり新しい機能を実装したりしながらコードを改善し続けます（新しいバグも追加してしまうかもしれません😅）。

### 小さなエラーは自動的に処理される { #small-errors-automatically-handled }

1. Creating a PR and observing the presubmit test results
2. Running the CI scripts locally, as explained below
3. **Google employees only**: Google employees can use an internal-only tool
called "MLCI" that makes testing more convenient: it can execute any full CI job
against a pending change. Search for "MLCI" internally to find it.

You may invoke a CI script of your choice by following these instructions:

```bash

As **FastAPI** is based on Starlette and implements the <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr> specification, you can use any ASGI middleware.

A middleware doesn't have to be made for FastAPI or Starlette to work, as long as it follows the ASGI spec.

In general, ASGI middlewares are classes that expect to receive an ASGI app as the first argument.

pkg encoding/json, method (*MarshalerError) Unwrap() error

    and match them against the toolchain requirements of the project (as configured in {@code pom.xml}):
    if match is found, the toolchain instance is made available to other Maven plugins.</p>
    <p>With {@code jdk} toolchain, for example, instead of being stuck with the JDK used to run Maven, all plugins can use
