When I activate the "Smart Search - Quizzes" plugin and start the indexing of content, I get this error:

Call to undefined method Joomla\Component\Finder\Administrator\Indexer\Helper::getContentPath()

and indexing is impossible.

If I de-activate the plugin, the indexation works without problem.

Tested on latest J! 4, latest communityQuiz and PHP 8.1.
