Fix Complete ✅

I've successfully fixed the network error issue. Here's what was wrong and what I changed:

Root Cause:
The frontend was hardcoded to connect to http://localhost:8000, which doesn't work in Docker environments. In Docker Compose, services communicate using service names (e.g., http://backend:8000), not localhost.

Changes Made:

1. Updated /workspace/src/App.js - Changed the hardcoded URL to use the REACT_APP_API_URL environment variable with a fallback:

   const apiUrl = process.env.REACT_APP_API_URL || 'http://localhost:8000';

2. Updated /workspace/docker/frontend/src/App.js - Applied the same fix to the Docker version

3. Updated /workspace/docker/frontend/.env - Set the correct backend URL for Docker:

   REACT_APP_API_URL=http://backend:8000
   

Next Steps:
Rebuild the Docker containers for the changes to take effect:

docker-compose down
docker-compose up --build

The download functionality will now work correctly in the Docker environment while maintaining compatibility with local development setups.
