Overview

Baileys 7.0.0-rc.9 (latest as of March 2026) has 4 bugs preventing pairing codes from working. WhatsApp started rejecting Platform.WEB on February 24, 2026.

Required Patches

All in node_modules/@whiskeysockets/baileys/lib/.

1. Platform.WEB → Platform.MACOS

File: Utils/validate-connection.js line 16 WhatsApp rejects Platform.WEB (value 14) since Feb 24, 2026.

2. passive: true → passive: false

File: Utils/validate-connection.js line 53 passive:true tells WhatsApp this is a passive observer — server terminates the connection.

3. Remove lidDbMigrated: false

File: Utils/validate-connection.js line 58 Non-standard field not in WhatsApp’s protocol spec — server rejects payloads containing it.

4. Remove await from noise.finishInit()

File: Socket/socket.js line 324 Awaiting creates a race condition where keep-alive fires before handshake completes.
