python - 在EB上部署结构化Flask应用程序 - 查看功能映射错误

我最近一直在努力将我的Flask应用部署到AWS ElasticBeanstalk。我对网络项目和AWS都很陌生，所以每天都很艰难。每隔一段时间我就会将我的项目部署到EB（过去我能够解决问题）但是由于我将我的应用程序从单片application.py重组为更加结构化的方法，我一直在努力。部署本身已成功，但我遇到了500错误。日志说：

我的应用结构是：

myApp/
   runServer.py
   requirements.txt
   app/
      __init__.py
      config.py
      static/
      members/
         __init__.py
         views.py
         models.py
      templates/

我的.ebextensions/<env-name>.config包含：

option_settings:
  "aws:elasticbeanstalk:container:python":
    WSGIPath: app/members/views.py

最后，我的views.py文件包含我的所有网址路由。我确保所有的函数名都是一样的。

有人知道我在看什么样的问题/解决方案吗？我可以提供更多信息来帮助吗？

谢谢！

修改：将def index()中的views.py功能更改为def newFunctionForTesting()会产生AssertionError: View function mapping is overwriting an existing endpoint function: newFunctionForTesting

编辑2：它可能类似于this one，但在这种情况下，建议的解决方案是将所有内容写入单个文件中，这不是我的方法寻找...也许蓝图可以更好地工作......

修改3 ：这是我的应用程序的样子。
