小程序备案的时候 一直报 86301系统错误，请稍后重试 这个究竟是什么错误，需要怎么才能找出对应的错误啊？

小程序申请备案报错{ "errcode": 86202, "hints": [ { "errcode": 86328, "err_field": "icp_subject.principal_info.certificate_photo_front", "errmsg": "无法读取图片识别内容，请尝试重新提交或重新上传图片" } ], "errmsg": "apply icp filing fail, hint: [0ad78957-db06-47f0-8622-dc0ad67c795a] rid: 650a7700-73ebaf0d-083d981e" 经检查上传的图片确实是所需的图片？有人知道是什么情况吗？

请问一下，做一个类似于58同城的小程序，帮一些商家发布经营的信息，但是小程序不涉及收款，是不是不需要什么资质就可以做？
