我正在尝试将 Django 项目连接到 MongoDB 集群，并且在运行时：

py manage.py runserver

或者

py manange.py migrate

它一直显示相同的错误：

Watching for file changes with StatReloader
Performing system checks...

System check identified no issues (0 silenced).

pymongo.errors.OperationFailure: unsupported type in filter

我的 setting.py 配置是：

DATABASES = {
'default': {
    'ENGINE': 'djongo',
    'NAME': 'database_django',
    'HOST': 'mongodb+srv://xxxxxx:aaaaaa@isssgeneral-sfm0v.mongodb.net/test?retryWrites=true&w=majority',
    'PORT': 27017,
    'USERNAME': 'xxxxxx',
    'PASSWORD': 'aaaaaa' 
}
}

我的python环境如下：

pymongo            3.7.0
Django             2.2.2 
djongo             1.2.32
sqlparse           0.2.4
dnspython          1.16.0

我已经尝试过这个建议将 pymongo 降级到 3.5.1 版本的帖子解决方案，该版本已经尝试过但没有奏效。事实上，该项目以前在 pymongo==3.7 版本（我目前在环境中拥有的那个）中工作。

我已经将这个 Django 项目配置为连接到本地服务器并且它可以工作，显然主机名有些不合适。集群配置没有问题（我认为），因为我有一个直接连接到同一个集群的 Jupyter Notebook。

真的不知道我的项目突然停止连接到我的MongoDB集群是怎么回事。任何人都可以帮助我找到解决这个问题的方法吗？

谢谢社区。
