API名称：WXApi sendAuthReq，微信版本：8.0.46，基础库版本：微信OpenSDK 2.0.2, 移动应用（APP）做微信登录

目前实现情况：点击微信登录，可以调起微信，确认之后，监听函数没有收到结果

注册WxApi成功，调用WXApi sendAuthReq(scope, state, nonAutomatic), 有几个log, 最后出错

2024-02-20 20:25:28.045204+0800 PTNS[600:63586] [WeChatIdentityHandler.mm]-[WeChatIdentityHandler checkAndRecordTokenToKeychain:contextID:error:]WXLog:Error:set token fail, errCode:4, errLog:wx token[] or contextId[(null)] is nil!

详细些的log是这样：

按照文档说明已验证universalLink可以正常工作。

请问最后这个出错可能是什么原因？
