我正在尝试为我的项目运行 celerybeat，但它给了我以下错误。
芹菜工人运行良好。
我正在使用Python 3.9
使用 MongoDB：6.0.11
raise ConnectionFailure(err_msg)
mongoengine.connection.ConnectionFailure: A different connection with alias `default` was already registered. Use disconnect() first

我尝试在连接 mongoengine 的代码中添加以下行
断开连接（）
但是没有成功。
现在我期待芹菜节拍应该运行。
尝试使用以下代码
import mongoengine
mongoengine.disconnect(alias='default')
mongoengine.connect('your-db-name', alias='default')
