开发者工具v1.03 2005140， node8.9，基础库2.2.5， 云函数代码中 import waterfall from 'aysnc/waterfall' 后本地调试只能加载左面的云函数列表，中间调试窗口和右边子窗口都空白无发硬。

注释掉import语句后调试器正常，但是报一个奇怪的语法错误， 说希望执行一个函数，实际上waterfall已经执行了。 上传图片总是失败，

以下是waterfall函数的输出

query:

/E:/wx/projs/wxminiProgCloud/cloudfunctions/ftpOper/index.js:85 db get err: TypeError: Cannot read property 'getTime' of undefined

/E:/wx/projs/wxminiProgCloud/cloudfunctions/ftpOper/index.js:28 save file cmp: [object Object]

/E:/wx/projs/wxminiProgCloud/cloudfunctions/ftpOper/index.js:18 mycallback

index.js:170 ftp connection had end

index.js:165 ftp connection had closed with err: false

代码如下，

     let i = 0

      ipCamMapArr = new Array()

      ipCamMap.forEach(function(key){

        ipCamMapArr[i] = {ip: key, filetime: ipCamMap.get(key)}

        i++

      })

      function cb(){console.log('cb,cb')}

      async.eachSeries(ipCamMapArr,

        function(item, cb){

          async.waterfall(

            [

            ftpGetPicFile(item, mycallback),

            savePicFile(item, mycallback),

            //checkPicFile(item, cb2),

            updateRec(item, mycallback)

          ],

          function(err, result){

            console.log('waterfall cb: ' + err + ', res: ' + result)

          }

          )

          cb()

        },

        function(err, result){

          console.log('eachofser cb: ' + err + ', res: ' + result)

        }

      )
