Error message

Invalid room

What it means

loadNextMessages throws error-invalid-room when rid is falsy. check(rid, String) already guaranteed the type, so this branch is reachable only with the empty string '' — any null/undefined/non-string would have failed check() with a Match error before reaching this line.

Solutions

1. Guard rid (non-empty string) before calling
2. Initialize rid from the room record/subscription and render loading state until it exists
3. Fail fast in development when rid is missing to catch state bugs

Example fix

// before
const { messages } = await Meteor.callAsync('loadNextMessages', rid, end, limit);

// after
if (typeof rid !== 'string' || rid.length === 0) {
  return { messages: [] }; // or await room load
}
const { messages } = await Meteor.callAsync('loadNextMessages', rid, end, limit);

if (typeof rid !== 'string' || rid.length === 0) {
  return { messages: [] }; // room id not ready yet
}

const isNonEmptyRoomId = (rid: unknown): rid is string =>
  typeof rid === 'string' && rid.trim().length > 0;

When it happens

Trigger: Meteor.call('loadNextMessages', '', end, limit) — rid read from an unset state field, an empty URL parameter, or a room subscription that has not delivered the record yet.

Common situations: Component renders before the room data arrives and passes an empty id; refactors that leave an intermediate variable uninitialized; optional route params used without a default.
