Common Issue Quick Fixes

If you encountered issues:

Backend won't start:

cd backend
rm -rf node_modules package-lock.json
npm install
npm start

Frontend won't start:

cd frontend
rm -rf node_modules package-lock.json
npm install
npm start

API keys not working:

  1. Verify keys are correct (no extra spaces)
  2. Restart servers after changing .env
  3. Check key has not expired
  4. Verify key has correct permissions

Cloudinary not working:

  1. Verify Cloud Name is correct
  2. Ensure upload preset is "Unsigned"
  3. Check preset name matches exactly
  4. Restart frontend

Next Steps

Once all checks pass:

  1. Experiment:

    • Try different input combinations
    • Test edge cases
    • Explore quality metrics

  2. Customize:

    • Modify refinement prompts
    • Adjust confidence thresholds
    • Customize UI styling

  3. Extend:

    • Add new perception modules
    • Integrate additional LLM providers
    • Implement caching
    • Add user authentication

  4. Deploy:

    • Choose hosting platform
    • Set up CI/CD
