Hi @Nightdragoon — sorry you hit that. Let me unpack what's going on.

What a LID is

LID stands for Linked Identity Device — it's WhatsApp's internal privacy-preserving identifier introduced with the multi-device protocol. Instead of addressing users by their raw phone number (+52 55 1234 5678), WhatsApp increasingly routes messages through a LID (a random-looking id like 12345:67@s.whatsapp.net). Your phone number is only resolved to a LID the first time there's any interaction (a message, a sync, a profile fetch).

Why you got "No LID for user"

This error means the engine couldn't resolve the phone number you tried to message to a LID. In older versions of OpenWA (which bundled Baileys 6.x), LID resolution for numbers you'd never contacted before was unreliable — WhatsApp's rollout of LID-based addressing broke the old resolution path.

The fix

We've since upgraded to @whiskeysockets/baileys@7.0.0-rc13 (shipped in recent releases, current as of v0.10.2), which has proper LID support. If you're on an older version, please pull the latest image and try again:

docker pull ghcr.io/rmyndharis/openwa:latest
docker compose up -d   # recreate the container

If the error persists on the latest version, it may be related to the known cold-contact first-send issue we're tracking in #830 — drop your OpenWA version + the exact phone format you're using there and we'll take a look.

Hope that helps!
