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>:

Right as we wanted it. ✔️

但输入**官方**链接 `/api/v1/docs`，并使用端口 `9999` 访问 API 文档，就能正常运行了！🎉

输入 <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 查看文档：</a>

一切正常。 ✔️

Auch wenn Ihr gesamter Code unter der Annahme geschrieben ist, dass es nur `/app` gibt.

  `I'm a poor man, your Majesty,' the Hatter began, in a
trembling voice, `--and I hadn't begun my tea--not above a week
or so--and what with the bread-and-butter getting so thin--and
the twinkling of the tea--'

  `The twinkling of the what?' said the King.

  `It began with the tea,' the Hatter replied.

  `Of course twinkling begins with a T!' said the King sharply.
