AI agent not using vector db to get information to answer to user

Hi! I’m having an error that i can’t solve in this n8n workflow.

The problem is AI agent not using the Supabase db to get information to answer to user. If i connect chat to Supabase node it works and returns the information. I’m a new n8n user and i would like to solve this.

Thank you.

I’ll close this. Solved.
