做的是小程序跳转到小程序客服功能，用户发送消息，服务器回复。

接受消息事件：{"Content":"hello","CreateTime":"1700448658","FromUserName":"oHi-y64GFZjnvIPOsm_tde3vjoTU","MsgId":"24344572565261857","MsgType":"text","ToUserName":"gh_54981f16f956"}

回复：{"touser":"oHi-y64GFZjnvIPOsm_tde3vjoTU","msgtype":"image","image":{"media_id":"M-rNfaw_yQyq5t2No8D0DqDQ82_f1hOBWXeULWHOr12cXdhuTnCzYtKSOGW1o0lo"}}

无效的openid：{"errcode":40003,"errmsg":"invalid openid rid: 655ac994-04022a2f-27ffa656"}

官方文档说FromUserName字段是openid，我原样返回就不可以？如何解决，真心累
