Error message

invalid user

What it means

`CloudAnnouncementsModule` (appId `cloud-announcements-core`) handles Rocket.Chat Cloud announcement banners. Its `viewClosed()` dismisses the announcement for the acting user and notifies Cloud, so it requires `payload.user._id`; when missing it throws a plain `Error('invalid user')` before any dismissal or Cloud call happens.

Solutions

1. Include `user: { _id: userId }` in the viewClosed payload.
2. For programmatic dismissal, call `Banner.dismiss(userId, bannerId)` from `@rocket.chat/core-services` directly instead of going through the module.
3. Verify the dispatcher (uiKit core app bus) attaches the current user to every interaction it forwards.

Example fix

// before
await announcementsModule.viewClosed({
  appId: 'cloud-announcements-core',
  payload: { view: { viewId: bannerId }, triggerId },
} as any);

// after
await announcementsModule.viewClosed({
  appId: 'cloud-announcements-core',
  user: { _id: userId },
  payload: { view: { viewId: bannerId }, triggerId },
} as any);

const canDismiss = (payload: UiKitCoreAppViewClosedPayload): boolean =>
  Boolean(payload.user?._id && (payload.payload?.view?.viewId || payload.payload?.view?.id) && payload.triggerId);

if (canDismiss(payload)) {
  await announcementsModule.viewClosed(payload);
}

function isCompleteAnnouncementClosePayload(
  payload: UiKitCoreAppViewClosedPayload,
): payload is UiKitCoreAppViewClosedPayload & { user: { _id: string }; triggerId: string } {
  return Boolean(payload.user?._id && payload.triggerId);
}

try {
  await announcementsModule.viewClosed(payload);
} catch (error) {
  if (error instanceof Error && error.message === 'invalid user') {
    return; // cannot attribute the dismissal to a user
  }
  throw error;
}

When it happens

Trigger: A `viewClosed` interaction for a cloud announcement banner where `payload.user` / `payload.user._id` is undefined — e.g. a synthetic payload from custom code, or an interaction dispatched after the user's session context was lost.

Common situations: Custom automation that closes announcement banners by dispatching UiKit events; test payloads built without the user field; stale clients after logout or session expiry.
