请问duckduckgo现在是调用不了了吗？

[YinSonglin1997]

升级duckduckgo版本解决

升级duckduckgo版本解决

请问您是否在建议使用高版本的 duckduckgo-search ? 能否开启一个PR？

我将xagentteam/toolserver-node镜像中的duckduckgo-search升级到3.9.10，解决了问题

max_workers must be greater than 0 这个问题和duckduckgo-search版本有关系吗？为啥我这边只看到那个错误，没看到duckduckgo-search的调用异常，而且我的toolserver-node中的duckduckgo-search版本已经到了4.1.0，似乎也不能再升了吧

死到这一步，不知道下一步怎么走呢

Hello guys!

I believe this issue is related to #344 .
Basically, the HTTP is not downloaded to the right version (i.e. httpx[http2] not httpx) and that cause the HTTP response output to be empty. The empty response output makes max_workers to be 0.

I'm not sure if this will work on Duckduckgo, but it works for me on the given default files that probably searched on common web explorer like Google, Bing, etc.

@ttran1904 @liruixue Can we schedule a meeting so that we can work together to locate the problem?

[ttran1904]

Yeah. I'm free right now. Just sent you an email

[ttran1904]

Also, if you're gonna use Duckduckgo, I recommend you guys to add duckduckgo-search==version numer in the 2 files:

1. ToolServer > ToolServerManager > requirements.txt
2. ToolServer > ToolServerNOde > requirements.txt

and not just pip install duckduckgo-search on the local computer, because it's not enough. I think the XAgent specifically uses packages in the Docker container, and the container only has packages specify in requirements.txt.
