### 작은 오류는 자동으로 처리됨 { #small-errors-automatically-handled }

FastAPI로 웹 API를 만들 때 코드에 오류가 있으면, FastAPI는 보통 그 오류를 발생시킨 단일 요청 안에만 문제를 가둡니다. 🛡

클라이언트는 해당 요청에 대해 **500 Internal Server Error**를 받지만, 애플리케이션은 완전히 크래시하지 않고 다음 요청부터는 계속 동작합니다.

### 더 큰 오류 - 크래시 { #bigger-errors-crashes }

그럼에도 불구하고, 우리가 작성한 코드가 **전체 애플리케이션을 크래시**시켜 Uvicorn과 Python 자체가 종료되는 경우가 있을 수 있습니다. 💥

* Validate that the `item_id` is of type `int` for `GET` and `PUT` requests.
    * If it is not, the client will see a useful, clear error.

    * As the `q` parameter is declared with `= None`, it is optional.
