    This file ends with no newline character, or with a different newline character than other files in your project. It won't render properly on a terminal, and it's considered a bad practice.

Your project should not contain PHP files defining multiple classes

More information: https://insight.symfony.com/what-we-analyse/php.file_contains_more_than_one_class

in config/reference.php
This file contains 2 classes. Keeping only one class per file is a standard in the PHP community, since it promotes interoperability and maintainability.
