При использовании `BackgroundTasks` (а не `BackgroundTask`), вам достаточно только определить параметр функции с типом `BackgroundTasks` и **FastAPI** сделает все за вас, также как при использовании объекта `Request`.

Вы все равно можете использовать `BackgroundTask` из `starlette` в FastAPI, но вам придется самостоятельно создавать объект фоновой задачи и вручную обработать `Response` внутри него.

            throwValidationErrorApi(messages -> messages.addErrorsFailedToUploadStopwordsFile(GLOBAL));

        return asJson(new ApiResult.ApiResponse().status(ApiResult.Status.OK).result());

### Small Errors Automatically Handled

When building web APIs with FastAPI, if there's an error in our code, FastAPI will normally contain it to the single request that triggered the error. 🛡

The client will get a **500 Internal Server Error** for that request, but the application will continue working for the next requests instead of just crashing completely.

### Bigger Errors - Crashes

  // DefaultRequest is the default resource requirement request value by resource name if resource request is omitted.
  // +optional
  map<string, k8s.io.apimachinery.pkg.api.resource.Quantity> defaultRequest = 5;

    public static final String ERRORS_APP_DB_ALREADY_EXISTS = "{errors.app.db.already.exists}";

    /** The key of the message: Your request might have been processed before this request. Please check and retry it. */
    public static final String ERRORS_APP_DOUBLE_SUBMIT_REQUEST = "{errors.app.double.submit.request}";

    /** The key of the message: Username or Password is not correct. */

* **Type checks**.

...en **FastAPI** gebruikt dezelfde declaraties om:

* **Vereisten te definïeren **: van request pad parameters, query parameters, headers, bodies, dependencies, enz.
* **Data te converteren**: van de request naar het vereiste type.
* **Data te valideren**: afkomstig van elke request:
    * **Automatische foutmeldingen** te genereren die naar de client worden geretourneerd wanneer de data ongeldig is.
