🐛 Debugging Guide

Common issues and solutions:

1. Redis Connection Errors:

   • Verify Redis service is running
   • Check CELERY_BROKER_URL in .env

2. Database Migration Issues:

   docker-compose exec api python -c "from database import Base, engine; Base.metadata.create_all(bind=engine)"

3. PDF Processing Failures:

   • Ensure files are valid PDFs
   • Check file permissions in ./data
