🚨 FIX SERVICE WORKER ERROR NOW

Your Error:

Loading from existing service worker.
main.dart.js:5658 Uncaught Error

Cause: Service worker is caching old/broken JavaScript code!


IMMEDIATE FIX (3 Steps)

Step 1: Clear Service Worker in Browser

  1. Press F12 to open DevTools
  2. Click Application tab (top)
  3. Click Service Workers (left sidebar)
  4. Find service worker for chitfund.deepteklabs.com
  5. Click Unregister
  6. Close DevTools

Method B: Clear All Site Data

  1. Press F12
  2. Go to Application tab
  3. Click Clear storage (left sidebar)
  4. Check all boxes
  5. Click Clear site data

Method C: Test in Incognito (Quick)

Windows: Ctrl + Shift + N
Mac: Cmd + Shift + N

Step 2: Deploy Fixed Version

# On your dev machine - push changes
git add .
git commit -m "Fix service worker caching issue"
git push origin prodnew

# SSH to production
ssh luckychit@192.168.8.148
cd /home/luckychit/apps/chitfund
git pull origin prodnew

# Rebuild (service worker now disabled)
cd luckychit
flutter clean
flutter pub get
flutter build web --release --pwa-strategy=none
pm2 restart luckychit-frontend

Step 3: Hard Refresh Browser

Windows: Ctrl + Shift + R
Mac: Cmd + Shift + R

What I Fixed

  1. Updated index.html - Now auto-clears service workers on load
  2. Updated all deployment scripts - Now build with --pwa-strategy=none (disables service worker)
  3. Updated documentation - Added service worker clearing to guides

🎯 Expected Result

After these steps, your browser console should show:

  • No "Loading from existing service worker" message
  • No "Uncaught Error"
  • App loads cleanly
  • Login screen appears

📋 Quick Checklist

  • Clear service worker in browser (F12 → Application → Unregister)
  • Push updated code to git
  • Pull on production server
  • Rebuild with --pwa-strategy=none
  • Restart PM2
  • Hard refresh browser
  • Verify no errors in console

💡 Why This Happened

Old deployment → Service Worker caches JS
    ↓
New deployment → New HTML served
    ↓
Service Worker → Serves OLD cached JS
    ↓
Old JS + New HTML = ERROR! ❌

🔄 From Now On

All your deployment scripts now:

  1. Build WITHOUT service worker (--pwa-strategy=none)
  2. Auto-clear any existing service workers
  3. Force cache refresh with timestamps

No more service worker issues! 🎉
