Before you upgrade to n8n 3.0
2 things in this workflow are removed in n8n 3.0. Fix them before you upgrade:
- OpenAI (legacy) in AI Fake Review Analysis: replace with OpenAI node (AI section).
- Function (legacy) in Generate Review Hash1: replace with Code node, mode 'Run Once for All Items'.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
