public function onRequestSetController(GetResponseEvent $event) {

  // Do not alter non-master request (this is a case when an exception is
  // thrown in controller).
  if (!$event
    ->isMasterRequest()) {
    return;
  }
  $request = $event
    ->getRequest();

  // Load asset by the request URI which is an asset alias. This call must
  // be as "lightweight" as possible as it will run before any other routes
  // are considered (it is still faster to run this before all RouterListener
  // processing).

    ->getRequestUri());
  $asset = Asset::loadByAlias($parsed_uri['path']);
  if ($asset) {
    $request->attributes

    $request->attributes
      ->set('asset_id', $asset
      ->id());

    // Stop further propagation as our raw URL has matched.
