How are you running AnythingLLM?

Docker (remote machine)

What happened?

When using Gemini as the LLM, trying to use the web search agent results in a 400 (No Body) error. Gemini is incredibly strict about the handshake during tool calls, so it's likely there's just something minor going on in the API. It's able to connect and make the initial search and retrieve results, but fails when handing those results off back to the LLM for rendering. I tried modifying some settings like GEMINI_SAFETY_SETTING and the LLM temperature to see if it was an issue the results themselves, but that made no difference.

I also confirmed that this problem goes away using other LLMs, such as Claude or ChatGPT, while leaving everything else the same.

Are there known steps to reproduce?

  1. Use AnythingLLM through the web interface (I did not verify if this issue exists in the desktop version)
  2. Set Gemini as the LLM provider (I specifically saw it with gemini-flash-latest)
  3. Enable the Web Search agent. I don't think the search provider matters. I reproduced it with Google, DuckDuckGo, and Tavily.
  4. Create a thread and invoke @agent with a search query
