调用提交审核接口，带上审核图片，请求参数如下

接口返回错误，错误信息 {"errcode":47001,"errmsg":"data format error rid: 6041d7e2-1efdd50a-141823cc"}

当我改成不带有审核图片，请求参数如下

此时可以请求成功

{"errcode":0,"errmsg":"ok","auditid":440636882}

我是按照官方文档格式上传的，官方接口地址 https://developers.weixin.qq.com/doc/oplatform/Third-party_Platforms/Mini_Programs/code/submit_audit.html

    },

    "ugc_declare": {
        "scene": [

            2
        ],
        "method": [
            1
        ],
        "has_audit_team": 1,
        "audit_desc": "blablabla"
    }
}

这个是官方请求参数例子，我发现请求格式一致。麻烦看下具体什么问题
