🐛 Troubleshooting

Tests Failing?

# Test against production
API_BASE_URL=https://aitmpl.com npm run test:api

# Check specific endpoint
curl -X POST https://aitmpl.com/api/track-download-supabase \
  -H "Content-Type: application/json" \
  -d '{"type":"agent","name":"test","path":"test/path"}'

Endpoint Not Found After Deploy?

1. Check Vercel function logs: vercel logs aitmpl.com --follow
2. Verify file is in /api root (not nested)
3. Ensure proper export: export default async function handler(req, res) {}

No Download Tracking Data?

1. Check Vercel logs
2. Verify environment variables are set
3. Test endpoint manually (see above)
4. Check Supabase table: select * from component_downloads order by created_at desc limit 10;
