Error message

Invalid room

What it means

Thrown by the 'messages/get' Meteor method when rid is falsy after the check(rid, String) match — in practice an empty string. The room id is the primary key for the history query, so an empty value cannot resolve to a room. Non-string values are rejected earlier by check() with a Match failed error instead.

Solutions

1. Pass the room's _id (not its name) and verify it is non-empty before calling
2. Derive rid from the user's subscription records when it is unknown
3. Guard the call site: if (!rid) return

Example fix

// before
Meteor.call('messages/get', rid ?? '', { lastUpdate });

// after
if (!rid) throw new Error('rid is required');
Meteor.call('messages/get', rid, { lastUpdate });

if (typeof rid !== 'string' || rid.trim() === '') {
  throw new Error('a non-empty room id is required');
}
Meteor.call('messages/get', rid, params);

function isValidRoomId(rid: unknown): rid is string {
  return typeof rid === 'string' && rid.length > 0;
}

try { await Meteor.callAsync('messages/get', rid, params); } catch (e) { if (e.error === 'error-invalid-room') { /* resolve rid from subscriptions and retry */ } }

When it happens

Trigger: Meteor.call('messages/get', '', { ... }); calling with a rid variable that is undefined-but-defaulted to '' or comes from an unset route param.

Common situations: Route handlers that read :rid from a URL before the subscription populates; deserialized state where the room id was never stored; passing a room name instead of the _id.
