vue3 click事件报错

问题描述:
在尝试在uniapp中使用vue3时点击事件报错. H5正常, 但在app中报错.

报错如下:
Uncaught TypeError: Cannot assign to read only property 'type' of object '#<MouseEvent>' at uni-app-view.umd.js:3

代码:

<!-- index.vue -->  
<template>  
    <view class="content">  
    <div class="cid-box">

      <div class="copy-cid" @click="copyCid">copy cid</div>  
    </div>  
    <div class="push-box">  
      <div class="type">push type is: {{type}}</div>
