The method scalarNode() does not exist on Symfony\Component\Config\Definition\Builder\NodeParentInterface. It seems like you code against a sub-type of Symfony\Component\Config\Definition\Builder\NodeParentInterface such as Symfony\Component\Config\Definition\Builder\NodeBuilder.

                    ->isRequired()
                    ->cannotBeEmpty()
                ->end()
                ->scalarNode('list_id')
                    ->isRequired()
                    ->cannotBeEmpty()
                ->end()
