我的mongo集群使用4.0版本，当我运行mongoexport -h 192.168.1.100 --port 8635 u exporter -p 'xxxxxxx' --readPreference nearest -d activity_account -c account_detail -o activity.json时，我正试图使用mongoexport导出带有json的集合。然而，几分钟后，进程退出，我收到一个错误，说CursorNotFound:

发生了什么事，我该如何解决？或者它有另一种导出到json的方法吗？
在我将mongoexport客户端更改为r4.0.24后，问题没有再次出现。在此之前，我有mongoServer4.0和mongoexport4.2
