Hey @kn0wledge,

We have created an internal ticket to look into this which we will be tracking as "N8N-8026"

Hi @kn0wledge -- Can you provide a bit more information? What Gemini model did you use? What tools did you connect to your agent? It would even work best if you can provide a minimal example as a JSON object. I was able to execute gemini 1.0-pro from n8n with a tool, and that worked fine.

Gemini might have issues with tools that don't have any parameters though, so if you have a tool that doesn't specify any parameters to specify from the agent, you may need to look into that.
