ROOT CAUSE FOUND
|
|
════════════════
|
|
🐛 parseInt() converting UUID strings to NaN
|
|
|
|
Backend sends: "3c9643cf-48bb-4684-8094-83757e624853"
|
|
Frontend did: parseInt("3c9643cf...") → NaN ❌
|
|
Profile lookup: profiles.find(p => p.id === NaN) → NEVER MATCHES!
|
|
|
|
PERMANENT FIX APPLIED
|
|
═══════════════════════
|
|
✅ Removed ALL parseInt() calls on profile IDs
|
|
✅ IDs kept as strings throughout entire app
|
|
✅ Backend returns full profile objects
|
|
✅ Works with BOTH numeric (1,2,3) AND UUID strings
|
|
|
|
