How to Fix Common Lovable Errors (Build, Deploy, GitHub)

Top Error Patterns

• Build fails after generated changes or dependency updates.
• Deploy fails due to environment/config drift.
• GitHub push/merge conflicts with generated changes.
• Runtime errors that pass generation but fail in production-like environments.

Fast Triage Checklist

• Lock Node/runtime version and reinstall dependencies cleanly.
• Verify required env vars and secrets are present for build and runtime.
• Run lint, typecheck, and tests before deploy.
• Split large generated change sets into smaller commits.
• Check framework-specific config changes (routing, build target, SSR/static output).

Fix by Symptom

1. Build Error After Generation

Usually caused by dependency mismatch, invalid imports, or stale lockfiles. Reinstall dependencies, pin versions, then rerun build with strict logs.

2. Deployment Error but Local Works

Check hosting target differences (SSR vs static), environment variables, and output directory config. Most failures are environment parity issues.

3. GitHub Push Rejected

Sync with remote first, resolve conflicts on small chunks, and avoid force-pushing generated mega-commits.

When to Stop Patching and Move to Feature1

• You are repeatedly fixing generation regressions.
• Features require structured planning and acceptance criteria.
• You need AC-by-AC implementation, PR traceability, and release notes.

At that point, move the repo into a production delivery workflow: Feature1 platform workflow.
