Error message

A Rocket.Chat App prevented the room erasing.

What it means

Before deleting, eraseRoom triggers the Apps Engine event IPreRoomDeletePrevent; if any loaded App's handler returns a truthy value, deletion is vetoed and this error is thrown. The veto is deliberate policy from an installed App, not a server bug.

Solutions

1. Identify the vetoing App: review installed Apps and which ones listen to IPreRoomDeletePrevent
2. Adjust the App's configuration/room filters so this room may be deleted, or disable/uninstall the App if the veto is unwanted
3. Contact the App maintainer if the veto looks unintentional

try {
  await eraseRoom(roomId, user);
} catch (err) {
  if (err instanceof Meteor.Error && err.error === 'error-app-prevented-deleting') {
    // an installed App vetoed the delete: inform the user, do not retry
    return;
  }
  throw err;
}

When it happens

Trigger: Any installed Rocket.Chat App implementing IPreRoomDeletePrevent (retention/legal-hold, DLP, archival apps) returns true when eraseRoom is called for a room it wants to keep.

Common situations: Compliance apps intentionally blocking deletion of retained rooms; an app bug vetoing every delete; app updated with stricter room filters.
