小程序app.onLaunch里获取用户信息，失败则跳转到err页面，代码如下

wx.getUserInfo({

    success: res => {

        that.globalData.userInfo = res.userInfo

        logger.info(‘app getUserInfo suss:’,res.userInfo)

    },

    fail: res => {

        logger.info(‘app getUserInfo fail’)

        that.globalData.errObj = that.getErrObj(‘获取用户标识失败’, res,101)

        wx.navigateTo({

            url: ‘/pages/index/err’,

            suss:res=>{

            logger.info(‘app navigateTo err suss’,res)

            },

            fail: res => {

            logger.info(‘app navigateTo err fail’, res)

            }

        })

    }

})

运行后能正确跳转到/pages/index/err页面，但是并没有打印出app navigateTo err suss或app navigateTo err fail，控制台报错

navigateTo with an already exist webviewId 197,位置介于err页面的onready和onshow之间。
