The method getSubject() does not exist on Symfony\Component\EventDispatcher\Event. It seems like you code against a sub-type of Symfony\Component\EventDispatcher\Event such as Symfony\Component\Security\Core\Event\VoteEvent or PhpSpec\Event\MethodCallEvent or PhpSpec\Event\ExpectationEvent or Symfony\Component\EventDispatcher\GenericEvent.

        /** @var Pagerfanta $data */
        $data = $resourceGridView->getData();

        return new PaginationParameterBag($resourceGridView->getRequestConfiguration()->getRequest(), $data->getNbResults(), $data->getMaxPerPage(), $data->getCurrentPage());
    }
}
