刚刚好了没几天，又出现了这样的问题了，还是云开发数据库watch监听的bug，请官方管理员来看一下。

下面是6月12日发的求助内容：

昨天上午还好好的，晚上就报错了。调试了整晚，手机端还是这个错误。偏偏在微信开发者工具上是正常的。

errCode: -402012 这个错误号，在帮助文档里面都找不到。

代码片段：

var db = wx.cloud.database();

var watcher1 = db.collection('game_rooms');

//监听游戏房间玩家信息更新情况：

      if (nowRoom.roomID != "" && G.inRoom == 1) {

        console.log("nowRoom.roomID",nowRoom.roomID);

        watcher1.where({

          _id: nowRoom.roomID

        }).watch({

          onChange: function(snapshot) {

           console.log('query result snapshot after the event', snapshot.docs);

          // 监听游戏房间数据：玩家1，玩家2，的信息，在此房间的游戏得分，剩余时间

  },

          onError: function (err) {

            console.error('the gameRoom watch1 closed because of error', err)

          }          

        });

      }
