Element UI Upload绑定action报错

Question

报错 Avoid using non-primitive value as key, use string/number value instead、

<el-upload

        class="upload-demo"
        :action="imgUrl"
        :data="upData"
        :on-success = "imgsuc"
        >
        

data: function(){

        return {
            imgUrl: '/edit/file.aspx?act=upload',
            upData:{
              sn :'b1'
            },
            num:1
        }
    },
    components: {
            VueCoreImageUpload
    },            

Answer 1

解决了么？我也碰到类似的问题，应该是key什么的问题？

Answer 2

 upData:{
          'sn' :'b1'        //应该是这里的sn要加引号 ===  use string/number value instead、
        },
