Schema errors

I attempted to reproduce this issue on my Drupal version 11.2, but was unable to do so. Please let me know if I may have missed any additional steps.

Drupal 11.2 offers the ConfigSchemaChecker in the development services. if activated, you'll get these warnings.

  logger.channel.config_schema:
    parent: logger.channel_base
    arguments: [ 'config_schema' ]
  config.schema_checker:
    class: Drupal\Core\Config\Development\LenientConfigSchemaChecker
    arguments:
      - '@config.typed'
      - '@messenger'
      - '@logger.channel.config_schema'
    tags:
      - { name: event_subscriber }
