Lagrange项目

OneBot

所使用/依赖的Lagrange项目对应的commit

903dce7

运行环境

Windows

运行架构

x64

连接方式

反向 WebSocket

重现步骤

Lagrange.OneBot_win-x64_net9.0，反向连接WS，分离部署的SealDice海豹核心。QQ隐私设置“加我为好友的方式”为“需要验证信息。任意帐号发送好友请求。

期望的结果是什么？

Lagrange像自动同意双相好友的进群邀请一样自动同意好友申请。

实际的结果是什么？

每次收到好友请求时会出现白字[WARN]报错，后台不会对此请求做更进一步处理。手机登录QQ后能看见未处理、待通过的好友申请等待审批。

简单的复现代码/链接（可选）

Trace 级别日志记录（可选）

（由”允许任何人的好友请求“、”需要正确回答问题“自动通过导致加上的单向好友的进群邀请也不会被处理）

海豹端已将加好友口令留空（即一切留言均可通过好友请求）。另，就算不开启海豹只开启Lagrange，也能复现一样的后台报错和QQ内效果

意识到这位用户并未提供完整的 trace 级别的log，故本人使用目前最新构建的 Lagrange.Onebot（ Commit 908683e ）在 Windows 11 .net 8.0环境进行复测，同样 bug 复现，trace级别log附此

error.log

初步检查该log报错，发现可能是与 Protobuf 序列化相关

在经过fork后初步排查与测试发现， #770 修改以后的 Lagrange.Onebot 程序在处理好友请求时会触发评论区所说的报错，而 #770 修改以前均可正常处理好友申请，特此补充一下。
