  2. Set Config (Edit Fields (Set)): sets 7 fields: userId, replyToken, userMessage…
  3. Load Chat History (Google Sheets): read rows
  4. Aggregate: combines items into one
  5. Study Agent (AI Agent): runs an AI agent, with model: Gemini Model; 1 tool (Search Materials Tool)

Before you upgrade to n8n 3.0

1 thing in this workflow is removed in n8n 3.0. Fix it before you upgrade:

Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
