Description

isRequired() is not compatible with a default value, as the default value is ignored. And exception should be thrown when a config tree node has both.

This can be deprecated in 7.4 and fail in 8.0.

Example

The following config tree should fail before processing a configuration.

$definition->rootNode()->children()    ->scalarNode('api_key')    ->defaultValue('%env(OPENAI_API_KEY)%')    ->info('OpenAI API Key used to authenticate with the OpenAI API');
