当我尝试向“http://{{MY IP}}:5000/alldocuments”发送 GET 请求时，出现错误。我正在关注 youtube 视频教程，甚至来自 github 的直接示例也不起作用。所有其他路线都有效，但我无法使这条路线有效。我无法在 SQLAlchemy 的文档中找到我的答案，但也许我只是想念它。我不知道出了什么问题？我正在传递带有附加数据的结果对象。
我在 youtube 上关注这个视频：https://www.youtube.com/watch ?v=PTZiDnuC86g
这是包含教程中完整代码的 github： https: //github.com/bradtraversy/flask_sqlalchemy_rest
我收到此错误：
