It seems like $fragmentName can also be of type null; however, parameter $name of Digia\GraphQL\Validation\ValidationContextInterface::getFragment() does only seem to accept string, maybe add an additional type check?

        if (null === $fragment) {
            $this->context->reportError(
                new ValidationException(unknownFragmentMessage($fragmentName), [$node->getName()])
