The function Symfony\Component\Config\Definition\Builder\TreeBuilder::root() has been deprecated: since Symfony 4.3, pass the root name to the constructor instead

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