在小游戏中调用客服功能，

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

var dt={

sessionFrom:"",

showMessageCard:false,

sendMessageTitle:"11",

sendMessagePath:"",

sendMessageImg:"",

success:(res)=>{

console.log(res);

},

fail: (res) => {

console.log(res);

},

complete: (res) => {

console.log(res);

},

}

wx.openCustomerServiceConversation(dt);

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`

报错：

Cannot read property 'nickname' of undefined;wx.openCustomerServiceConversation

TypeError: Cannot read property 'nickname' of undefined

请问nickname在哪啊，是个什么鬼？
