예외를 잡고 그에 기반해 사용자 정의 응답을 생성하려면, [사용자 정의 예외 처리기](../handling-errors.md#install-custom-exception-handlers)를 생성하세요.

## `yield`와 `except`를 사용하는 의존성 { #dependencies-with-yield-and-except }

`yield`를 사용하는 의존성에서 `except`를 사용하여 예외를 포착하고 예외를 다시 발생시키지 않거나 (또는 새 예외를 발생시키지 않으면), FastAPI는 일반적인 Python에서와 마찬가지로 예외가 있었다는 것을 알아차릴 수 없습니다:

例外をキャッチして、それに基づいてカスタムレスポンスを作成したい場合は、[カスタム例外ハンドラ](../handling-errors.md#install-custom-exception-handlers)を作成してください。

## `yield`と`except`を持つ依存関係 { #dependencies-with-yield-and-except }

`yield`を持つ依存関係で`except`を使って例外をキャッチし、それを再度raiseしない（または新しい例外をraiseしない）場合、通常のPythonと同じように、FastAPIは例外があったことに気づけません:
