What Ollama model are you running? A lot of the smaller local models dont handle tool calling well so the agent never actually passes a search query to SerpAPI, it just sends empty input.
Hi @Majdi_Bsoul Welcome!
Have you tried using this node to work with SerpAPI:
https://www.npmjs.com/package/n8n-nodes-serpapi
Yeah so qwen2.5:7b is the problem, it returned 0 completion tokens which means it’s not generating proper tool calls. Try switching to a bigger model like qwen2.5:14b or llama3.1:8b (the instruct variant) since those handle tool use much better. The 7b qwen model is just too small to reliably format tool calling output.
