⭐ Priority: MEDIUM

Session Goal:

The session aimed to improve the stability and functionality of the FastAPI backend and address API fetch issues in a React component.

Key Activities:

1. FastAPI Backend Enhancements:

   • Cleaned and rewrote api/main.py to improve error handling, logging, and CORS settings.
   • Refactored api/router.py to address import and wiring issues, enhancing code structure and stability.
   • Refactored flow_backend.py for better structure, organization, and security, preparing it for production.

2. React API Debugging:

   • Diagnosed and fixed a fetch call issue in a React component, focusing on an undefined flowPath causing malformed requests.
   • Proposed solutions for API fetch issues, including using the backend URL directly or configuring a proxy in next.config.js.

Achievements:

• Successfully refactored key components of the FastAPI backend, enhancing overall application stability and developer experience.
• Identified and proposed solutions for API fetch issues in React, improving the reliability of frontend-backend communication.

Pending Tasks:

• Integrate the refactored backend components into the production environment.
• Implement the proposed solutions for API fetch issues in the React application.
