Summary

Fixed a critical authentication display issue where logged-in users could not see their email address in the TopBar components on both desktop and mobile views. The issue was caused by attempting to access userProfile.email, which doesn’t exist in the user_profiles table schema.

Problem

Users reported that after logging in, they couldn’t see their login status (e.g., “anthony@happycode.ch”) in the TopBar. This affected both desktop and mobile views across all three sites.

Root Cause

The TopBar components were trying to access userProfile.email as a fallback, but the user_profiles table schema doesn’t include an email field. The email is only available in the authentication session object at session.user.email.

Changes

Bug Fixes

• TopBar.tsx (React component): Removed userProfile.email from fallback chain

  • Changed from: {userProfile.email || session.user?.email || 'User'}
  • Changed to: {session.user?.email || 'User'}

• TopBar.astro (all three apps): Updated email display logic

  • happycode-ch: Fixed desktop dropdown display
  • intellidoc-ch: Fixed desktop dropdown display
  • promptlab-ch: Fixed desktop dropdown display

Technical Details

• Authentication Data Structure:

  • session.user.email: Contains the user’s email address ✓
  • userProfile.email: Does not exist in schema ✗
  • userProfile: Contains user preferences and permissions

• Display Logic: Now correctly uses only session.user?.email for email display

Impact

• ✅ Logged-in users now see their email address in the TopBar
• ✅ Desktop dropdown shows correct email (e.g., “anthony@happycode.ch”)
• ✅ Mobile menu shows correct email in account section
• ✅ All three sites (happycode, intellidoc, promptlab) affected
• ✅ No breaking changes to existing functionality

Testing

• Desktop view: User email displays correctly in dropdown
• Mobile view: User email displays correctly in menu
• All three sites show proper authentication status
• Sign out functionality remains intact
• Non-logged-in users still see “Sign In” buttons
• VERIFIED: Fix confirmed working across all sites by user

Resolution Status

✅ CONFIRMED WORKING - User has verified that the authentication display now works correctly across all three sites (happycode, intellidoc, promptlab) on both desktop and mobile views. Users can now see their logged-in status with their email address displayed properly in the TopBar components.

Centralized Favicon and Logo System
