It seems like $this->container can also be of type null; however, parameter $container of Symfony\Component\DependencyInjection\Compiler\ServiceLocatorTagPass::register() does only seem to accept Symfony\Component\DependencyInjection\ContainerBuilder, maybe add an additional type check?

        $value->addTag('container.service_subscriber.locator', ['id' => (string) $locatorRef]);

            PsrContainerInterface::class => new BoundArgument($locatorRef, false),
            ServiceProviderInterface::class => new BoundArgument($locatorRef, false),
        ] + $value->getBindings());

        return parent::processValue($value);
