📋 Decision Context

Question:

How to fix the 404 error when loading module catalog from backend?

Task: Fix loadModuleCatalog() 404 error - use correct API endpoint path

🎯 Decision Made

Chosen:

Use /ai-api/ prefix to route to backend-ai-api (port 3001)

Options Considered:

1. Comment out the code (previous agent approach)
2. Move CatalogController to backend-api (port 3000)
3. Use /ai-api/ prefix to route to backend-ai-api (port 3001)

💭 Reasoning

The CatalogController is registered in backend-ai-api which runs on port 3001. The frontend was using ${this.apiBaseUrl}/catalog/modules which routes to the main backend (port 3000). The codebase has an established pattern where AI-related endpoints use /ai-api/* prefix, which is proxied to port 3001 via proxy.conf.json. Rather than commenting out working code or moving controllers, the fix is to use the correct endpoint path: /ai-api/catalog/modules.
