昨天运行还正常；最近云开发控制平台v1.4.49 和 v1.4.50 运行云数据库监听功能都正常；

但今天就不行了；查找原因：是云开发控制平台居然回退到v1.4.38这个版本；简直是无语😐啦。

开发云数据库监听的技术官方文档：

https://developers.weixin.qq.com/miniprogram/dev/wxcloud/guide/database/realtime.html#%E7%9B%91%E5%90%AC

错误信息如下：

the watch closed because of error Error: errCode: -402006 realtime listener receive server error msg | errMsg: ACL_CHANGE_ERROR - user acl has changed!

history states: UNINIT-(loginStart)->INIT_LOGGING_IN-(loginSuccess)->INIT_LOGGED_IN-(initWatchStart)->INIT_WATCH_PENDING-(initWatchSuccess)->INIT_WATCH_SUCCESS-(close)->CLOSED
