解决langchain-chatchat-0.3.0版本互联网搜索报错BUG_str type expected

 本篇文章是基于langchain-chatchat-0.3.0配置好bing_key的前提下，出现下面的报错，这个位置上对源码进行修改，方可以正常使用网络搜索。

这个时候我们需要在/root/miniconda3/envs/chatchat_0.3.0/lib/python3.11/site-packages/chatchat/webui_pages/dialogue/dialogue.py，这个文件中的dialogue/dialogue.py在420行的位置上，将下面的代码替换掉之前的代码，就可以解决启动不了网络搜索页面报错的问题

这里个需要注意的点是，先不要勾选页面上的agent功能。 修改之后，最后成功运行如下：

最后成功运行如下：
