Method ReflectionParameter::getClass() is deprecated in PHP 8

I want to report this error.

PHP Deprecated: Method ReflectionParameter::getClass() is deprecated in /wp-content/plugins/2fas-light/vendor/php-di/php-di/src/Definition/Source/ReflectionBasedAutowiring.php on line 65

Just to note, it looks like they have a beta3 release that supports PHP 8 – https://github.com/PHP-DI/PHP-DI/releases – and a milestone for the prod release – https://github.com/PHP-DI/PHP-DI/milestone/22

Is this package needed in production? Is there a work-around for PHP 8? Thanks!
