RouteObjectInterface not found in new install

As per the linked change record, symfony-cmf/routing has been deprecated. The solution is to change the reference to \Drupal\Core\Routing\RouteObjectInterface.

I was able to work around the issue on my local instance by changing line 176 of the january.theme file to:

  if ($route = $request->attributes->get(\Drupal\Core\Routing\RouteObjectInterface::ROUTE_OBJECT)) {
    $title = \Drupal::service('title_resolver')->getTitle($request, $route);
    $variables['page__title']=strip_tags($title);
  }

The fix in #2 worked for me. Thanks!

Hi @bogdog400
Fixed the issue & generated the MR, please review.

I installed the latest dev version with composer:

composer require 'drupal/january_theme:1.0.x-dev@dev'

It runs fine. The theme installs and displays without an error.

Thanks!

If anyone looking for a patch for the current composer version, I have attached a patch for version 1.01

Thanks It worked for me.
