But if we access the docs UI at the "official" URL using the proxy with port `9999`, at `/api/v1/docs`, it works correctly! 🎉

You can check it at <a href="http://127.0.0.1:9999/api/v1/docs" class="external-link" target="_blank">http://127.0.0.1:9999/api/v1/docs</a>:

But FastAPI also supports using <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> the same way:

```Python hl_lines="1  7-12  19-20"
{!../../../docs_src/dataclasses/tutorial001.py!}
```

```Python hl_lines="1-3"
{!../../../docs_src/python_types/tutorial010.py!}
```

Тогда вы можете объявить переменную типа `Person`:

```Python hl_lines="6"
{!../../../docs_src/python_types/tutorial010.py!}
```

И снова вы получаете полную поддержку редактора:
