use Digia\GraphQL\Language\AST\Node\ListValueNode;

The method getValues() does not exist on Digia\GraphQL\Language\AST\Node\NodeInterface. It seems like you code against a sub-type of Digia\GraphQL\Language\AST\Node\NodeInterface such as Digia\GraphQL\Language\AST\Node\EnumTypeDefinitionNode or Digia\GraphQL\Language\AST\Node\EnumTypeExtensionNode or Digia\GraphQL\Language\AST\Node\ListValueNode.

        return wrap('[', implode(', ', $values), ']');
    }

    /**
     * @inheritdoc
     */
    public function supportsWriter(NodeInterface $node): bool
    {
        return $node instanceof ListValueNode;
    }
}
