Solo puedes usar `await` dentro de funciones creadas con `async def`.

///

---

Si estás usando un paquete de terceros que se comunica con algo (una base de datos, una API, el sistema de archivos, etc.) y no tiene soporte para usar `await` (este es actualmente el caso para la mayoría de los paquetes de base de datos), entonces declara tus *path operation functions* como normalmente, usando simplemente `def`, así:

```Python hl_lines="2"
@app.get('/')

import org.codelibs.fess.app.service.FileAuthenticationService;
import org.codelibs.fess.app.service.FileConfigService;
import org.codelibs.fess.app.web.CrudMode;
import org.codelibs.fess.app.web.base.FessAdminAction;
import org.codelibs.fess.helper.SystemHelper;
import org.codelibs.fess.opensearch.config.exentity.FileAuthentication;
import org.codelibs.fess.opensearch.config.exentity.FileConfig;

import org.codelibs.fess.app.service.RequestHeaderService;
import org.codelibs.fess.app.service.WebConfigService;
import org.codelibs.fess.app.web.CrudMode;
import org.codelibs.fess.app.web.base.FessAdminAction;
import org.codelibs.fess.helper.SystemHelper;
import org.codelibs.fess.opensearch.config.exentity.RequestHeader;
import org.codelibs.fess.opensearch.config.exentity.WebConfig;

Isso é especialmente útil para uma **base de código grande** onde **as mesmas dependências** são utilizadas repetidamente em **muitas *operações de rota***.

## `Async` ou não, eis a questão
