Hi,

I'm using the quiz module version 6.0.0-alpha7 with Drupal 9.4.2.

When I try to go to Quiz > Question (/admin/quiz/questions), I got this fatal error :

Error: Cannot instantiate abstract class Drupal\quiz\Entity\QuizQuestion in /srv/data/web/vhosts/dev.fr/htdocs/core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php on line 509 #0 /srv/data/web/vhosts/dev.fr/htdocs/core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php(427): Drupal\Core\Entity\Sql\SqlContentEntityStorage->mapFromStorageRecords()

Has anyone encountered the same error before?

Kind regards,

Getting the same error with 9.5.9. Once you get this error you wont see questions bank anymore. For unistalling quiz I also had to delete manually all the questions from db...

I've encountered this issue after upgrading to Drupal 10 and believe it could be related to the following: https://www.drupal.org/node/3191609 → . I'm using an older and quite modified version of the Quiz module, however, so I cannot provide my solution as a patch at this time.
