The method getServiceLocator() does not exist on Zend\ServiceManager\ServiceLocatorInterface. It seems like you code against a sub-type of Zend\ServiceManager\ServiceLocatorInterface such as Zend\ServiceManager\AbstractPluginManager.

            $container->get(CommandBusInterface::class),
            new DoctrineRepository(Delegate::class, $container->get(EntityManager::class))
        );
