• The class MailLogger has two parameters that are fed in the module's services.yml file:

hello_world.logger.mail_logger:
    class: Drupal\hello_world\Logger\MailLogger
    arguments: ['@logger.log_message_parser', '@config.factory']
    tags:
      - { name: logger }

• I don't understand why the 2 parameters of MailLogger are considered missing ?
  • and where the MailLogger is called in the Module hello world

1. Your first point of contact should be the author of that code, who got paid to write that code. That is the person who should be providing the support.
2. Search the internet. If that code is faulty, then there will certainly be a bug report somewhere that reports the same error as you. If you can't find a similar report, chances are the problem is on your end and not with the code.
3. That code seems to be written for Drupal 9.0. That is not the current version of Drupal. If you are using as more current version of Drupal, it's entirely possible that changes to Drupal have caused that code to stop working. Use the version of Drupal that the code was designed for and see if it works there. If it does, then the code needs to be updated.
4. If you have changed the code in any way, like changing the name of the module, then again chances are you've done something wrong. Don't make any changes at all, no matter how trivial, until after you get the code running.
