Mission Control Documents Fix - Summary

Problem

Documents page stuck on "Loading documents..." indefinitely even though API endpoint /api/documents was working correctly.

Root Cause Analysis

The API endpoint was properly configured and environment variables were set on Vercel. The issue was that:

1. The API route was already fixed with proper error handling
2. The useDocuments hook had good error handling but lacked a timeout mechanism
3. The issue was likely related to fetch hanging or taking too long without proper timeout handling

Changes Made

1. Updated hooks/useDocuments.ts

• Added fetchWithTimeout helper function with 10-second timeout
• Added abort controller to cancel fetch if it takes too long
• Added proper cleanup with isMounted flag to prevent state updates after unmount
• Improved console logging with [useDocuments] prefix for easier debugging
• Added better error handling for timeout scenarios

2. Verified app/api/documents/route.ts

• API route already had proper environment variable validation
• Returns clear error messages if env vars are missing
• Uses service role key for Supabase access

Verification

• API endpoint returns all 3 documents correctly from Supabase
• Build succeeds without errors
• Deployed to production successfully

Deployment URLs

• Production: https://mission-control-rho-pink.vercel.app
• API Test: https://mission-control-rho-pink.vercel.app/api/documents

Next Steps (for user)

1. Visit https://mission-control-rho-pink.vercel.app/documents in browser
2. Check browser console for [useDocuments] log messages
3. If still stuck on loading, check Network tab to see if fetch is completing
4. If there's an error, the page should now display it with a retry button
