//这样子传能接到,但是response, file, fileList都拿不到了,上传成功回调都不执行了
<el-upload :on-success="handleEvaSuccess(Groupindex)">    
handleEvaSuccess(index,response, file, fileList) {
    console.log(response, file, fileList)
},

试试这个

:on-success="(res, file)=>handleBannerSuccess(res, file, Groupindex)"

handleBannerSuccess(response, file, index) {  
    console.log(response, file, index);   
}
