Solutions

1. Check the subscription's roles array includes 'leader' before calling removeRoomLeader; skip the call otherwise.
2. Refresh the room's leader list in the UI after any role change to avoid acting on stale data.

Example fix

const sub = await Subscriptions.findOneByRoomIdAndUserId(rid, userId);
if (sub?.roles?.includes('leader')) {
  await Meteor.callAsync('removeRoomLeader', rid, userId);
}

When it happens

Trigger: Thrown by `removeRoomLeader` (removeRoomLeader.ts:48) when the target user's subscription has a roles array that does not include 'leader', i.e. the user is a room member but does not currently hold the leader role.

Common situations: Leader role was already removed; user was never a leader; concurrent role changes.
