Solutions

1. Only create invite links for channels and groups; direct messages and other room types do not support invite links.
2. Check room.t before calling findOrCreateInvite and reject unsupported types early.

When it happens

Trigger: Thrown when findOrCreateInvite is called for a room type that does not support invite links (e.g. direct messages or other non-channel/group types).

Common situations: See trigger scenarios.
