@NanaXiong00 Thanks for the report! could you check that Ollama is working correctly? I frequently have to restart it manually because of updates. You can check if it works by running the command:

ollama run mistral

If the model starts and you can chat with it, it should be good. If not, try restarting Ollama.

From the logs, it also seems that you tried testing the chat before the document where ingested (running npm run upload:docs). Seems like the ingestion worked, did you try again the chat after that?

Follow the above reply and test again. The problem cannot be reproduced, so I closed it.
