🔥 FIXING "Loading 6D Dashboard..." ISSUE

🎯 THE PROBLEM

Dashboard never loads - just stuck on "Loading 6D Dashboard..." spinner forever

🔍 ROOT CAUSE ANALYSIS

The issue is typically one of these:

1. React not rendering - JavaScript error during component initialization
2. Missing component - Import path broken
3. Infinite loading state - Redux state not updated
4. CSS error - Theme/styling breaks layout
5. Network timeout - API call hanging
6. Module resolution - Path alias not resolving

🚀 QUICK FIX I JUST IMPLEMENTED

Step 1: Added Error Boundaries

✅ Updated index.html with global error handlers ✅ Updated main.tsx with try-catch around render ✅ Shows actual error messages instead of stuck spinner

Step 2: Created Debug Test Component

✅ Created DebugTest.tsx - minimal component to verify React renders ✅ Temporarily switched to DebugTest in main.tsx ✅ This isolates the issue

Step 3: What to Do Now

Option A: See What Error Exists

1. Run: npm run dev
2. Open browser to http://localhost:3000
3. If DebugTest page shows with "✅ React is rendering correctly!" → React works, problem is in Dashboard component
4. If you still see "Loading..." → Problem is in React setup (check console for error)
5. If you see red error box → Error details shown - report that error

Option B: Check Browser Console

1. Open Developer Tools (F12 or Cmd+Option+I)
2. Go to Console tab
3. Look for red errors - copy them here
4. Also check Network tab - are requests failing?

Option C: Check Common Issues

Check 1: Missing Redux Selectors

// In dashboard-6d/index.tsx, around line 15-20:
// Make sure all these exist in sixd.selectors.ts:
selectSixDOverview;
selectLoading;
selectError;
selectFocus;
selectSelectedSheet;
selectAllDisciplines;

Check 2: Missing Theme CSS

// In main.tsx:
// Should see: generateAuroraCss() and generateLcarsCss()
// injected to document.head

Check 3: ThorSixDClient Methods

// In thor.client.ts, must have:
getHealth() ✓
getDisciplines() ✓
getOverview() ✓

📋 FILES I MODIFIED

File	Change	Why
index.html	Added error handlers + better display	Shows actual errors instead of stuck spinner
main.tsx	Added try-catch + debug logging	Catches init errors, logs progress
DebugTest.tsx	Created new debug component	Minimal test to verify React works

🎯 NEXT STEPS

If DebugTest Works

→ Problem is in Dashboard component → Switch back to AppRouter in main.tsx → Add console.logs to dashboard-6d/index.tsx → Log each render phase

If DebugTest Fails

→ Problem is in build/bundling → Check vite.config.ts for errors → Rebuild: npm run build → Check for TypeScript errors: npm run type-check

If You See an Error Box

→ Copy the error message
→ Check which file/line is failing → Fix that specific import/component

🎓 HOW TO DEBUG FURTHER

In Browser Console:

// Check if Redux store exists:
console.log(window.__REDUX_DEVTOOLS_EXTENSION__);

// Check if React is loaded:
console.log(React);

// Check if main.tsx logged:
// Look for: "[MAIN] Starting React render..."

Run with Debug Mode:

# In apps/6d-dashboard:
npm run dev -- --debug

# Watch logs in terminal

---

🔄 TO RESTORE FULL DASHBOARD

Once you confirm DebugTest works, edit src/main.tsx:

// Change:
<DebugTest />

// Back to:
<AppRouter />

// Also restore import:
import AppRouter from './app/router';

Then rebuild and test.

⚠️ COMMON SOLUTIONS

Problem: Cannot find module...
→ Check @ alias in vite.config.ts
→ Verify file path is correct

Problem: Redux error
→ Check all selectors export in sixd.selectors.ts
→ Verify store config in main.tsx

Problem: Blank white page
→ CSS not loading
→ Check generateAuroraCss() works
→ Check @import statements in css files

Problem: Spinner keeps spinning
→ Async code never completes
→ Check ThorSixDClient.getOverview() returns data
→ Check Redux dispatch(setOverview()) works

---

📝 ACTION ITEMS

1. ✅ Run npm run dev in apps/6d-dashboard
2. ✅ Open browser to http://localhost:3000
3. ✅ Check if DebugTest page shows OR you see an error
4. ✅ Report what you see
5. ✅ If DebugTest works, I'll switch back to real dashboard with fixes
