Why this happens
Build errors in your code — TypeScript issues, missing dependencies, or configuration problems.
Fix
Read the error
Vercel Dashboard → Deployments → click failed build → scroll to the first red line. The error tells you exactly what's wrong.
Common fixes
Match the error to the fix:
Error: Cannot find module 'X' Fix: npm install X — commit package.json Error: Type error in X.tsx Fix: Fix the TypeScript error in your code Error: Build timeout Fix: Check for infinite loops in build scripts
Prevent this next time
Run npm run build locally before pushing to Vercel. If it builds locally, it'll build on Vercel.
