Upon submitting a quiz with a multiple choice question I get a WSOD.
In the logs is:
Warning: Undefined array key 0 in Drupal\quiz_maker\Plugin\QuizMaker\Response\MultipleChoiceResponse->setScore() (line 34 of /www/modules/contrib/quiz_maker/src/Trait/SimpleScoringResponseTrait.php)
Followed by:
Error: Call to a member function getPluginInstance() on null in Drupal\quiz_maker\Plugin\QuizMaker\Response\MultipleChoiceResponse->setScore() (line 36 of /www/modules/contrib/quiz_maker/src/Trait/SimpleScoringResponseTrait.php).
Create a quiz with a multiple choice question
Take the quiz, observe upon submission the above errors occur.
Looks like the array keys of $answers on line 34 of SimpleScoringResponseTrait.php is not 0 based, rather keyed by entity ID of the answers.

Please check the warning pipelines, all of them should be passed and then I will merge it
