我在配置 CKAN 插件时得到用户不可迭代

Question

我在 CKAN 上工作，我使用了一个扩展来通过 Azure Active Directory 对我的 CKAN 进行身份验证，我得到了

TypeError: cannot unpack non-iterable NoneType object

我联系了扩展开发人员，但我没有得到开发人员的任何回应。 这是我的 GitHub 问题：https://github.com/ongov/ckanext-msal/issues/4#issuecomment-1445794423

我正在使用这个扩展：https://github.com/ongov/ckanext-msal.git 这是我的日志：

Traceback (most recent call last):
  File "/srv/app/src_extensions/ckanext-msal/ckanext/msal/plugin.py", line 98, in get_a_token
    user_id = model.User.get(user_name).id
AttributeError: 'NoneType' object has no attribute 'id'

During handling of the above exception, another exception occurred:
