Essa exceção será manipulada, contudo, pelo `unicorn_exception_handler`.

Dessa forma você receberá um erro "limpo", com o HTTP status code `418` e um JSON com o conteúdo:

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

/// note | "Detalhes Técnicos"

Você também pode usar `from starlette.requests import Request` and `from starlette.responses import JSONResponse`.

Но оно будет обработано `unicorn_exception_handler`.

Таким образом, вы получите чистую ошибку с кодом состояния HTTP `418` и содержимым JSON:

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

/// note | "Технические детали"

Также можно использовать `from starlette.requests import Request` и `from starlette.responses import JSONResponse`.
