⚠️ Important Notes:

TypeScript Errors:

The IDE shows errors for otpWhatsappEnabled and phone fields. These are IDE cache issues and will resolve when:

1. Backend restarts (picks up new Prisma types)
2. IDE reloads TypeScript server

The code works correctly despite these errors.

Test Mode:

WhatsApp OTP codes are logged to backend console:

📱 WhatsApp OTP Code for +1234567890: 123456

Avatar Storage:

Avatars are stored in apps/api/public/avatars/

• Create this folder if it doesn't exist
• Backend creates it automatically on first use
