调用getUserProfile()报错，会报获取不到头像信息的错误？

代码如下， 报错见附件：

<template>  
  <view>  
      <button @tap="wxGetUserProfile">  
          授权  
      </button>  
  </view>  
</template>  

<script>  
import { AppModel } from '@/models/app.js';  
const appModel = new AppModel();  

export default {  
    name: 'UserInfoBtn',  
    methods: {  
        wxGetUserProfile: function () {  
            return new Promise((resolve, reject) => {  
              uni.getUserProfile({  
                lang: 'zh_CN',  
                desc: '获取你的昵称、头像、地区及性别',  
                success: (res) => {  
                    console.log('成功', res)  
                  resolve(res)  
                },  
                // 失败回调  
                fail: (err) => {  
                    console.log('失败', err)  
                  reject(err)  
                }  
              })  
            })  
         },  
    }  
}  
</script>  

<style lang="scss" scoped>
