Yes， I meet the same problem； ----》LIghtRAG
I choose the Ollama local embedding LLM and chat Siliconflow API，occur like that；
then I changed the chat LLM on default setting page（Chat Ollama LLM ,Deepseek-r1:7b）, it works;
May be its a API connection bug;

I have the same problem, but I launched from source code. Is there currently a solution for this? Thanks.

[KevinHuSh]

Pull the latest code.

[Borye]

Solved thanks.
