  ActionListener.wrap(
  rollupConfigPersistentTask -> waitForRollupStarted(job; listener; persistentTasksService);
  e -> {
  if (e instanceof ResourceAlreadyExistsException) {
  e = new ElasticsearchStatusException("Cannot create job [" + job.getConfig().getId() +
  "] because it has already been created (task exists)"; RestStatus.CONFLICT; e);
  }
