Error message

Invalid room

What it means

unblockUserMethod loads both subscriptions in the room — the blocked user's and the blocker's — via Subscriptions.findOneByRoomIdAndUserId; if either is missing it throws error-invalid-room. Despite the code name, the usual meaning is not 'bad rid' but 'one of the two users is not (or no longer) a member of this room'.

Solutions

1. Verify both users still have subscriptions in the room before offering the unblock action
2. Refresh room/membership state from the server when the action fails rather than retrying blindly
3. Pass rid from the currently open room context, never from persisted state

Example fix

// before
await unblockUserMethod(userId, { rid, blocked }); // error-invalid-room after the target left

// after
const [blockedSub, mySub] = await Promise.all([
  Subscriptions.findOneByRoomIdAndUserId(rid, blocked, { projection: { _id: 1 } }),
  Subscriptions.findOneByRoomIdAndUserId(rid, userId, { projection: { _id: 1 } }),
]);
if (!blockedSub || !mySub) throw new Meteor.Error('error-invalid-room', 'Invalid room');
await unblockUserMethod(userId, { rid, blocked });

import { Subscriptions } from '@rocket.chat/models';

const [target, self] = await Promise.all([
  Subscriptions.findOneByRoomIdAndUserId(rid, blocked, { projection: { _id: 1 } }),
  Subscriptions.findOneByRoomIdAndUserId(rid, userId, { projection: { _id: 1 } }),
]);
if (!target || !self) {
  // hide the unblock action; membership changed
}

try {
  await unblockUserMethod(userId, { rid, blocked });
} catch (error) {
  if (error instanceof Meteor.Error && error.error === 'error-invalid-room') {
    // refetch subscriptions and update the member list UI
  } else {
    throw error;
  }
}

When it happens

Trigger: Calling the unblockUser method after the blocked user left the room; using a rid from stale client state (the UI switched rooms); invoking unblock in a context where the caller has no subscription to rid.

Common situations: Direct-message member lists kept in client state after the other party leaves; races between leave-room and moderation actions; wiring the rid parameter from the wrong room.
