Punarchakra - Project Summary
Punarchakra is a Smart E-Waste Management System with a Next.js frontend (Vercel) and Express/MongoDB backend (Render). It features AI-powered waste detection, QR code login for kiosks, rewards/gamification, and push notifications.

The Deployment Struggles
I faced a persistent “Failed to fetch” NextAuth error that took several debugging iterations to solve:

Environment Variables: NextAuth v5 requires AUTH_SECRET (not NEXTAUTH_SECRET) and AUTH_TRUST_HOST=true.
Conditional Google OAuth: Made Google login optional to prevent crashes when credentials are invalid.
The Real Culprit: A rewrite rule in
vercel.json
was redirecting ALL /api/* requests to an external URL, including the NextAuth routes that needed to stay on Vercel!
Lesson learned: Always check your routing configuration when API routes mysteriously fail - rewrites can silently break your authentication flow.
