问题描述

我在尝试使用 Flagger 查看 Swagger UI 时收到此错误消息：

 ERROR in app: Exception on /apispec_1.json [GET]
Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/flask/app.py",line 2446,in wsgi_app

    if not getattr(item,'get'):
AttributeError: 'nonetype' object has no attribute 'get'

我尝试了所有方法，但是当我访问 http://localhost:5000/apidocs 时我什么也看不到。我收到错误消息：获取错误：内部服务器错误 /apispec_1.json
