TypeError: Cannot read properties of undefined (reading 'markedUnread') during message sending

[utavukcu]

Describe the bug I am encountering a 500 Internal Server Error when trying to send a message via the API. The session status is CONNECTED, but the message is not delivered, and the logs show a TypeError related to markedUnread.

Error Message:

JSON
{
"success": false,
"error": "Cannot read properties of undefined (reading 'markedUnread')\nI (https://static.whatsapp.net/rsrc.php/v4ivYF4/yv/l/en_GB-j/PYyXh1NyTG4.js:1541:4171)"
}
Environment:

OS: AlmaLinux 8 / 9

Deployment: Docker

Base Image: node:22-bookworm-slim

Browser: Chromium (System installed)

wwebjs-api Version: Latest (Main branch / Edge)

whatsapp-web.js Version: github:pedroslopez/whatsapp-web.js#main

Configuration (.env):

SET_MESSAGES_AS_SEEN=false

SET_MESSAGES_AS_READ=false

WEB_VERSION_CACHE_TYPE=none

Steps to Reproduce:

Start a session via /session/start/test.

Scan the QR code and confirm the status is CONNECTED.

Try to send a message using /client/sendMessage/test.

The API returns the markedUnread error, and the message is not sent.

Additional Context: It seems that even with SET_MESSAGES_AS_SEEN=false, the library still attempts to call a function that relies on markedUnread, which has likely changed in the latest WhatsApp Web update (v2.3000.x). I have tried a clean build with --no-cache and using the edge version of whatsapp-web.js, but the issue persists.

@avoylenko if we update the failing latest docker image to the one with tage edge you mentioned, will the solution work regardless of the WEB_VERSION set in .env ?

docker pull avoylenko/wwebjs-ap:edge

Thanks

@AKhateeb i can not guarantee that. Whatsapp team pushed many changes in the recents weeks.
