Deployment Failures with AI-Generated Projects

AI-generated code often works locally but fails during deployment. Common issues include missing environment variables, incorrect build configurations, incompatible dependencies, and misconfigured hosting platforms.

Common Symptoms

  • Build succeeds locally but fails on Vercel/Netlify/Cloudflare
  • Missing environment variables causing runtime errors
  • TypeScript errors only appearing during production build
  • Docker/container configuration issues
  • CORS errors after deployment
  • Serverless function timeouts or cold start issues

Try These Fixes First

Before hiring an agency, try these steps yourself. Many common issues can be resolved with the right approach.

1

Verify all environment variables are set in your hosting platform

2

Run production build locally (npm run build) before deploying

3

Check for Node.js version mismatches between local and hosting

4

Review build logs for the specific error message

5

Ensure all API endpoints use correct production URLs

6

Add proper error handling for missing env vars at startup

Frequently Asked Questions

Why does my AI-generated app fail to deploy?

AI tools develop in an environment different from production. They may hardcode localhost URLs, skip environment variable validation, use dev-only dependencies, or generate code that passes type checks loosely but fails strict builds.
