**FastAPI** использует его для того, чтобы, если вы используете Pydantic-модель в `response_model`, и ваши данные содержат ошибку, вы увидели ошибку в журнале.

Но клиент/пользователь этого не увидит. Вместо этого клиент получит сообщение "Internal Server Error" с кодом состояния HTTP `500`.

**FastAPI** faz uso dele para que você veja o erro no seu log, caso você utilize um modelo de Pydantic em `response_model`, e seus dados tenham erro.

Contudo, o cliente ou usuário não terão acesso a ele. Ao contrário, o cliente receberá um "Internal Server Error" com o HTTP status code `500`.
