 client.get(get; ActionListener.wrap(r -> onGetFinishedTaskFromIndex(r; listener); e -> {
 if (ExceptionsHelper.unwrap(e; IndexNotFoundException.class) != null) {
 // We haven't yet created the index for the task results so it can't be found.
 listener.onFailure(
 new ResourceNotFoundException("task [{}] isn't running and hasn't stored its results"; e; request.getTaskId())
 );
 } else {
 listener.onFailure(e);
 }
 }));
