vue element upload 上传报错，怎么实现upload 上传到服务器

Question

上传老是报错这个
Avoid using non-primitive value as key, use string/number value instead.

这个错误是我哪里的值写错了额？

<el-form-item label="图片" >
    <el-upload
        class="upload-demo"
        drag
        action="http://www.youxia.com/yxcard/admin.php?s=/Activity/edit_activity"
        :data="form.upLoadData"
        :file-list="form.fileList"
        :onError="uploadError"
        :onSuccess="uploadSuccess"
        :before-upload="beforeUpload"
        :on-change="handleChange"
        multiple>
        <i class="el-icon-upload"></i>
        <div class="el-upload__text">将文件拖到此处，或<em>选择文件</em></div>
        <div class="el-upload__tip" slot="tip">请上传jpg/png文件，且不超过500kb</div>
