We also verify that we have a user with that username, and if not, we raise that same exception we created before.

## Verify the `scopes`

We now verify that all the scopes required, by this dependency and all the dependants (including *path operations*), are included in the scopes provided in the token received, otherwise raise an `HTTPException`.

あなた（または使用しているライブラリ）が`raise`するかもしれないカスタム例外`UnicornException`があるとしましょう。

そして、この例外をFastAPIでグローバルに処理したいと思います。

カスタム例外ハンドラを`@app.exception_handler()`で追加することができます:

```Python hl_lines="5 6 7  13 14 15 16 17 18  24"
{!../../docs_src/handling_errors/tutorial003.py!}
```

ここで、`/unicorns/yolo`をリクエストすると、*path operation*は`UnicornException`を`raise`します。

しかし、これは`unicorn_exception_handler`で処理されます。

                return message  # pragma: no cover

            body_len = len(message.get("body", b""))
            received += body_len
            if received > self.max_content_size:
                raise HTTPException(
                    422,
                    detail={
                        "name": "ContentSizeLimitExceeded",
                        "code": 999,
                        "message": "File limit exceeded",
