## Context
This issue needs to be fixed by an AI agent.

## Requirements
- Analyze the issue description
- Implement appropriate fix
- Ensure frontend and backend compilation works
- Test thoroughly

## Repository Structure
- backend/: Backend code
- frontend/: Frontend code
- scripts/: Utility scripts

## Instructions
1. Read the issue carefully
2. Implement the fix
3. Verify both frontend and backend compilation
4. Document changes made
