// 小程序appid: wxa8934a297add4681
wx.openCustomerServiceChat({
      extInfo: {url: 'https://work.weixin.qq.com/kfid/kfc62a2ed3853a08f82'},
      corpId: 'ww5b92079fc80e4ae9',
      success(res) {},
      fail(err){
        console.log(err);
        wx.showModal({
          content: JSON.stringify(err),
          cancelColor: 'cancelColor',
        })
      }
})

麻烦大佬看看，{errCode: 6, errMsg: "openCustomerServiceChat:fail not bind"}，该如何操作呢？
