Jacob Paris (@jacobparis) · 2025-05-16 You're overriding the `/recommend` route in your vercel.json. I would suggest not using `routes` there Instead, if you're looking at redirecting traffic, you should use [rewrites](https://vercel.com/docs/project-configuration#rewrites) to send visitors to `/recommend` to your `/api/recommend-lambda` system (@system) · 2026-01-20 Hey @aifusion24-gmailcom! 👋 Just wanted to follow up here. If you've found a solution or still need help, let us know! We're happy to continue assisting.
