使用docker部署也是发生相同报错

使用docker部署也是发生相同报错

你看一下你的docker在报这个错的时候有没有自动重启的日志记录？我今天手动关闭的UI页面，也是报ERROR: Exception in ASGI application，所以我推测应该是异常中断导致的错误。我咩有仔细看代码，说实话我可能也不太能看得懂，不过docker是经常容易因为程序运行异常自动重启的。

我这边感觉不太像是异常中断，应该是Tavily没有正确返回内容导致结构化定义的Tavily返回消息缺失：

但是在webui右侧已经搜索出结果：

一直卡在如图所示的界面；

一个月之前的版本还可以运行，拉取了最新的代码之后就跑不了了

TAVILY_API_KEY也已正确配置：
