Vercel Deployment Debugging

Workflow

1. Check authentication

vercel whoami

If error "No credentials found", prompt user to run vercel login in their terminal (interactive).

2. List recent deployments

vercel list <project-name> --scope <team-name>

Find the failing deployment URL (status: Error or Building).

3. Get build logs

vercel inspect <deployment-url> --logs --scope <team-name>

Add --wait to wait for in-progress builds:

vercel inspect <deployment-url> --logs --scope <team-name> --wait

4. Common errors

Error	Cause	Fix
Mixed Routing Properties	`routes` and `rewrites` mixed in vercel.json	Use only `rewrites` (new format)
Cannot find module	Package not built before dependent	Add to build command or use turbo
Build Command > 256 chars	Command too long	Use `pnpm build` with turbo/nx

5. Get deployment info (without logs)

vercel inspect <deployment-url> --scope <team-name>
