Getting the right content from Supabase Q&A Table/DB

Describe the problem/error/question

Hi, I’m trying to build a KB of Q&A assistant. I created and imported a base with the columns topic and answer. When I ask in the chat, the answer is responded generally by OpenAI instead of the content I have in the table.

What is the error message (if any)?

No error, just wrong content

Hey @RodrigoC

It doesn’t look like your Supabase table is a vector table so it might just be you’re using the wrong tool. Instead of the “Vector Store Tool”, try just the “Supabase Tool” instead.

RAG is just an approach to building with AI agents, vector stores are optional.
