We started seeing this error recently. We used this feature before and it was working. Settings we recently changed was to use the LoginKey in the URL and force2factor: true.
Chat windows are open on both sides and the error shows up on both chat windows, too.
We tried to remove the LoginKey and force2factor configuration, even so the error occurs. It is probably not related to this configurations.
We tried to update Mesh Central to 0.6.54, too. Even so, not working this feature.
I'm getting the same issue, I've updated to 0.6.54.
Edit: not sure if should be posted as new issue or should reopen : https://github.com/Ylianst/MeshCentral/issues/1728
Looking into this now.
Your right, I am seeing the same problem. Working on it.
Fixed it, will be in MeshCentral v0.6.55.
Just perfect, updated and resolved. Tks, Ylian.
