Custom Module using Breadcrumbs as a Service - main methode (applies()) is not getting implemented.

Hey all,

I am working on a custom module that displays events. The events come from a remote service and I to set the breadcrumbs for the Events (list) page and the individual event page.

The individual event page works as intended (siteName/Events/EventName), however the event (list) page does not work (siteName/Events). Using devel_dump and echo, I am able to see what is executing, the _Construct executes, but the applies() method does not fire in my EventsBreadcrumbsBuilder class.

I think it has something to do with my route.

I'm including all file info.

Here are the two routes:

my_events.routing.yml

#List page for this site's events
my_events.events:
  path: '/events/{view}/{date}/{cat}'
  defaults:
    _title: 'Events'
    _controller: '\Drupal\my_events\Controller\RemoteEventsController::eventsListView'
    view: 'week'
    date: 'now'
    cat: '0'
  requirements:
    _access: 'TRUE'
  options:
    no_cache: 'TRUE'

#Single event page
my_events.event:
  path: '/event/{id}'
  defaults:
    _title: 'Event'
    _controller: '\Drupal\my_events\Controller\SingleRemoteEventController::content'
  requirements:
    _access: 'TRUE'
    id: \d+
  options:
    no_cache: 'TRUE'

my_events.service.yml file

services:
  my_events.breadcrumb:
    class: Drupal\my_events\Breadcrumb\EventsBreadcrumbBuilder
    arguments: ['@config.factory']
    tags:
      - { name: breadcrumb_builder, priority: 100 }

    if (str_contains($route_name, 'my_events') === FALSE) {
      return FALSE;
    } else {
      return TRUE;
    }

  }

  /**

  public function build(RouteMatchInterface $route_match) {

    // Get the site config, so we can access the site name.
    $site_name = $this->configFactory->get('system.site')->get('name');
    $func = new EventFunctions();
    $breadcrumb = new Breadcrumb();

    // Add a link to the homepage as our first crumb.
    $breadcrumb->addLink(Link::createFromRoute($site_name, '<front>'));
    $breadcrumb->addLink(Link::createFromRoute('Events', 'my_events.events'));
    $route_name = $route_match->getRouteName();

    if ($route_name == 'my_events.event') {
      /* Get Event information from external source
       * Returns an array with breadcrumb items ['id', 'event_title']
      */
      $bc_items = $func->getBreadcrumbItems($route_name);
      $id = $bc_items[1];
      $breadcrumb->addLink(Link::createFromRoute($bc_items['label'], 'my_events.event', ['id' => $id]));
    }
    // Don't forget to add cache control by a route.
    // Otherwise all pages will have the same breadcrumb.
    $breadcrumb->addCacheContexts(['route']);

    // Return object of type breadcrumb.
    return $breadcrumb;
  }

}

Any ideas are welcome.
