首先，感谢您花时间阅读本文。过去我的格式不是最好的，所以这次我会做得更好。
前言：我对 api/node.js 领域非常陌生，甚至对 heroku 也很陌生。我在互联网上搜索并应用了大约 30 次提交价值的更改，并取得了不同形式的成功。
我的问题是，有没有人对如何克服这个问题有任何建议、想法和指导？ 2021-01-11T17:54:19.095682+00:00 heroku[router]: at=info method=GET path="/" host=november-td-ameri.herokuapp.com request_id=d2cb2e61-8b9c-4490 -928d-a41d1e9e9dcb fwd="85.217.133.162" dyno=web.1 connect=0ms service=20ms status=404 bytes=383 protocol=https
