Type Error on ContainerAwareEventDispatcher

yes, just change

use Drupal\Component\EventDispatcher\ContainerAwareEventDispatcher;

for

use Symfony\Contracts\EventDispatcher\EventDispatcherInterface;

and change the constructor like:

public function __construct(
  array $configuration,
  $plugin_id,
  $plugin_definition,
  ConfigFactoryInterface $config,
  CacheBackendInterface $cache,
  TimeInterface $time,
  EventDispatcherInterface $event_dispatcher, // <-- here the magic
  ClientInterface $http_client,
  Token $token,
  LoggerInterface $logger
) {
  parent::__construct($configuration, $plugin_id, $plugin_definition);

  $this->config = $config;
  $this->cache = $cache;
  $this->time = $time;
  $this->eventDispatcher = $event_dispatcher;
  $this->httpClient = $http_client;
  $this->token = $token;
  $this->logger = $logger;
}

and done :-D
