## Recent Bug Fixes

### PDF Upload Issue Resolution
**Timeline**: December 25, 2025
**Commits**: 910bd525, 9ab09196, 8027ef0a

1. **Network Issue** - Frontend couldn't reach backend
   - Root cause: Docker network isolation
   - Fix: Added frontend to app-network

2. **MIME Type Issue** - PDFs rejected by validation
   - Root cause: Strict MIME type checking
   - Fix: Enhanced validation for multiple PDF MIME types

3. **Form Data Issue** - Missing required fields
   - Root cause: Incomplete FormData construction
   - Fix: Added title, summary, notes fields

## Next Steps

### Immediate (User Action Required)
1. **Redeploy containers** in Portainer to apply fixes
2. **Test PDF upload** functionality
3. **Monitor logs** for any remaining issues

### Future Enhancements (Potential)
- Bulk document upload
- Document versioning
- Advanced search functionality
- Email notification improvements
- Mobile app development

## Development Notes

### Key Learnings
- Docker network configuration critical for container communication
- Browser MIME type detection varies, need flexible validation
- Form validation must match backend requirements exactly
- Production logging essential for debugging

### Best Practices Applied
- Systematic debugging approach
- Comprehensive error logging
- Proper Git commit messages
- Network connectivity testing
- End-to-end validation

The website is now fully functional with all major features working correctly.
