在小游戏中调用客服功能，

<span style="color: #0000ff;">var</span> dt={

sessionFrom:<span style="color: #a31515;">""</span>,

showMessageCard:<span style="color: #0000ff;">false</span>,

sendMessageTitle:<span style="color: #a31515;">"11"</span>,

sendMessagePath:<span style="color: #a31515;">""</span>,

sendMessageImg:<span style="color: #a31515;">""</span>,

success:(res)=&gt;{

console.log(res);

},

fail: (res) =&gt; {

console.log(res);

},

complete: (res) =&gt; {

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<span style="white-space: pre-wrap;">nickname在哪啊，是个什么鬼？</span>
