python aumentum_api.py
```

### 2. Start the Next.js App
```bash
cd /home/katie/Desktop/PLAGIS_AUMENTUM/plagis-nextjs
npm install  # if needed
npm run dev
```

### 3. Test the Search
1. Navigate to `http://localhost:3000/dashboard`
2. Click on "Party" section in the sidebar
3. Enter search criteria (e.g., Last Name: "Ihemere")
4. Click "Search"
5. View results in expandable cards

## Support

If you encounter any issues:
1. Check that the API server is running on port 8001
2. Verify database connection is working
3. Check browser console for frontend errors
4. Review API logs for backend errors
5. Ensure JWT token is valid

For database-related issues, check:
- Database connection string in `.env`
- Database permissions for the user
- Table structure matches schema
