[WEBJS] - api/sendSeen not working on Chromium and Chrome (WEBJS), but works fine on NO Browser (NOWEB)

api/sendSeen not working on Chromium and Chrome (WEBJS), but works fine on NO Browser (NOWEB)

Already tested with all available options. When running a Chromium and Chrome (WEBJS) version, api returns 201 created, with the response as "1" - when messageId informed, or { ids: null } - when messageId not informed.

When running a NO Browser (NOWEB) version, it works fine - messageId informed or not.

Version

{
  "version": "2025.7.5",
  "engine": "WEBJS",
  "tier": "WAHA+"
}

Steps

To Reproduce Steps to reproduce the behavior:

1. Run Chrome or Chromium version
2. Send POST api/sendSeen
3. Response: 201 created - 1 or { ids: null }
4. WhatsApp message NOT marked with double blue ticks

Expected behavior

1. Run Chrome or Chromium version
2. Send POS api/sendSeen
3. Response: 201 created - { "ids": ["false_123456789@c.us_3AA1E240B683A31777C1"] }
4. WhatsApp message marked with double blue ticks

Do you guys know what is really happening?

If we don't mark the message as seen BEFORE we send a new message, we could be flaged as a bot and being blocked.

2025.7.6 - WEBJS - fix send seen and send read messages - #1117

[devlikepro]

201 created - { "ids": ["false_123456789@c.us_3AA1E240B683A31777C1"] }

in WEBJS engine ids is always null, you can read all messages in the chat only
