(A.) After QRcode Scan, I got this message from the server:

sending {"from": "backend", "timestamp": 1662277391920, "resource_instance_id": "d2f1959831024e54a9394877ea831ebb", "message": ["Cmd", {"version": "2.2126.11", "type": "upgrade_md_prod"}], "type": "whatsapp_message_received", "message_type": "json"}

[0] }

After digging a bit in the WA web code, it seems this message indicates that the client needs to be upgraded to the mulit-device version.
what could be the possible solution to it?

(B) Also whatsapp websocket is using wss://web.whatsapp.com/ws/chat gateway instead of wss://web.whatsapp.com/ws gateway. And When I tried to update the gateway to 'wss://web.whatsapp.com/ws/chat' client doesn't establish connection with ws. But the wss://web.whatsapp.com/ws gateway works to establish connection but can't proceed after QRscan and sending response with message: ["Cmd", {"version": "2.2126.11", "type": "upgrade_md_prod"}]

Am I configuring it wrong?

Note: I'm using WHATSAPP_WEB_VERSION="2,2232,8"
And to avoid hard code for WA web version add this line:

import requests
res = requests.get('https://web.whatsapp.com/desktop/mac/releases').json()
WHATSAPP_APP_VERSION = res['name']

Apparently this project doesn't work on "multi device", so it won't work with devices that already enabled this feature. You could check https://github.com/pokearaujo/multidevice instead.
