以下代码用实时数据推送，在微信开发者工具及手机端都能正常稳定运行。

但在Windows的环境下，当isClosedLoop = true正常运行，但当isClosedLoop = false则报错，不知道什么原因？

代码：

      let isClosedLoop
      if (that.data.currentTabs == 'processing') {
        isClosedLoop = false
      } else {
        isClosedLoop = true
      }


      const db = wx.cloud.database()
      const _ = db.command


      console.log('[需求列表] : 开始监听')
      const watcher = db.collection('support').orderBy('createTime', 'desc').limit(that.data.supportListLimit)
        .where(_.and({
          closedLoop: isClosedLoop
        }, _.or({
          frontlineOpenId: that.data.loginInfo.staffOpenId
        }, {
          supportOpenId: that.data.loginInfo.staffOpenId
        })))
        .watch({
          onChange: function (snapshot) {
            console.log(snapshot)
          },
          onError: function (err) {
            console.error('the watch closed because of error', err)
          }
        })

在Windows的环境下，当isClosedLoop = false报错：
