🔧 Fixes Applied

1. Backend: auth.controller.ts (Line 221)

Issue: Property 'sub' does not exist on type 'UserPayload'

Fix: Changed user.sub to user.id and added complete user fetch from database

@Get('me')
async getProfile(@CurrentUser() user: UserPayload) {
  // Fetch complete user details from database
  const fullUser = await this.userRepository.findById(user.id);

  if (!fullUser) {
    throw new NotFoundException('User not found');
  }

  // Return complete user data with firstName and lastName
  return UserMapper.toDto(fullUser);
}

Location: apps/backend/src/application/controllers/auth.controller.ts

2. Frontend: auth-context.tsx

Issue: TypeError: Cannot read properties of undefined (reading 'logout')

Fix: Changed imports from non-existent authApi object to individual functions

// OLD (broken)
import { authApi } from '../api';
await authApi.logout();

// NEW (working)
import {
  login as apiLogin,
  register as apiRegister,
  logout as apiLogout,
  getCurrentUser,
} from '../api/auth';
await apiLogout();

Added: refreshUser() function for manual user data refresh

const refreshUser = async () => {
  try {
    const currentUser = await getCurrentUser();
    setUser(currentUser);
    if (typeof window !== 'undefined') {
      localStorage.setItem('user', JSON.stringify(currentUser));
    }
  } catch (error) {
    console.error('Failed to refresh user:', error);
  }
};

Location: apps/frontend/src/lib/context/auth-context.tsx

3. Frontend: Dashboard Layout

Added: Debug component and NotificationDropdown

import NotificationDropdown from '@/components/NotificationDropdown';
import DebugUser from '@/components/DebugUser';

// In header
<NotificationDropdown />

// At bottom of layout
<DebugUser />

Location: apps/frontend/app/dashboard/layout.tsx

4. Frontend: New Components Created

NotificationDropdown

• Real-time notifications with 30s auto-refresh
• Unread count badge
• Mark as read functionality
• Location: apps/frontend/src/components/NotificationDropdown.tsx

DebugUser (Temporary)

• Shows user object in real-time
• Displays localStorage contents
• Fixed bottom-right debug panel
• Location: apps/frontend/src/components/DebugUser.tsx
• ⚠️ Remove before production

📋 Complete Data Flow

Login Flow

1. User submits credentials → Frontend calls apiLogin()
2. Backend authenticates → Returns { accessToken, refreshToken, user }
3. Frontend stores tokens → localStorage.setItem('access_token', token)
4. Frontend stores user → localStorage.setItem('user', JSON.stringify(user))
5. Auth context updates → Calls getCurrentUser() to fetch complete profile
6. Backend fetches from DB → UserRepository.findById(user.id)
7. Returns complete user → UserMapper.toDto(fullUser) with firstName, lastName
8. Frontend updates state → setUser(currentUser)
9. Dashboard displays → Avatar initials, name, email, role

Token Storage

// Auth tokens (for API requests)
localStorage.setItem('access_token', accessToken);
localStorage.setItem('refresh_token', refreshToken);

// User data (for display)
localStorage.setItem('user', JSON.stringify(user));

Header Authorization

Authorization: Bearer {access_token from localStorage}

🧪 Testing Steps

1. Frontend Test

1. Open http://localhost:3000/login
2. Login with:
   • Email: test4@xpeditis.com
   • Password: SecurePassword123
3. Check if redirected to /dashboard
4. Verify user info displays in:
   • Sidebar (bottom): Avatar with "JD" initials, "John Doe", "test4@xpeditis.com"
   • Header (top-right): Role badge "ADMIN"
5. Check Debug Panel (bottom-right black box):
   • Should show complete user object with firstName and lastName

2. Debug Panel Contents (Expected)

🐛 DEBUG USER
Loading: false
User: {
  "id": "138505d2-a2ee-496c-9ccd-b6527ac37188",
  "email": "test4@xpeditis.com",
  "firstName": "John",
  "lastName": "Doe",
  "role": "ADMIN",
  "organizationId": "a1234567-0000-4000-8000-000000000001"
}

3. Browser Console Test (F12 → Console)

// Check localStorage
localStorage.getItem('access_token')  // Should return JWT token
localStorage.getItem('user')          // Should return JSON string with user data

// Parse user data
JSON.parse(localStorage.getItem('user'))
// Expected: { id, email, firstName, lastName, role, organizationId }

4. Network Tab Test (F12 → Network)

After login, verify requests:

• ✅ POST /api/v1/auth/login → Status 201, response includes user object
• ✅ GET /api/v1/auth/me → Status 200, response includes firstName/lastName

🐛 Troubleshooting Guide

Issue: User info still not displaying

Check 1: Debug Panel

Look at the DebugUser panel (bottom-right). Does it show:

• ❌ user: null → Auth context not loading user
• ❌ user: { email: "...", role: "..." } but no firstName/lastName → Backend not returning complete data
• ✅ user: { firstName: "John", lastName: "Doe", ... } → Backend working, check component rendering

Check 2: Browser Console (F12 → Console)

localStorage.getItem('user')

• ❌ null → User not being stored after login
• ❌ "{ email: ... }" without firstName → Backend not returning complete data
• ✅ "{ firstName: 'John', lastName: 'Doe', ... }" → Data stored correctly

Check 3: Network Tab (F12 → Network)

Filter for auth/me request:

• ❌ Status 401 → Token not being sent or invalid
• ❌ Response missing firstName/lastName → Backend database issue
• ✅ Status 200 with complete user data → Issue is in frontend rendering

Check 4: Component Rendering

If data is in debug panel but not displaying:

// In dashboard layout, verify this code:
const { user } = useAuth();

// Avatar initials
{user?.firstName?.[0]}{user?.lastName?.[0]}

// Full name
{user?.firstName} {user?.lastName}

// Email
{user?.email}

// Role
{user?.role}
