[BUG]Messages stuck in PENDING state when sending to specific contact JIDs on v7.0.0-rc.8

[sosofire]

Sending a message to a WhatsApp contact always results in the message state being PENDING.

Example of the resulting message node:

[{
  "key": {
    "remoteJid": "244972480xxx@c.us",
    "fromMe": true,
    "id": "3EB0F23BF143F535FF52B9"
  },
  "message": {
    "extendedTextMessage": { "text": "hi" }
  },
  "messageTimestamp": "1763605640",
  "status": "PENDING"
}]

When I try to send to:
244972480xxx@s.whatsapp.net
the status remains PENDING forever.

When I call the send-message method, the parameter I pass is 244972480xxx@c.us, not 244972480xxx@s.whatsapp.net.
