Quiz result migration in D8 from D7

This now works for me, would be great if more people could use their testset to test the migration process.

Here is a patch with a rebase of the above MR with the current 6.x-dev

Example JSON to use the 'plain diff' link from the issue fork to patch the quiz package in a composer.json file with the "cweagans/composer-patches" package installed.

"patches": {
    "drupal/quiz": {
      "Quiz result migration in D8 from D7 - 3181926": "https://git.drupalcode.org/project/quiz/-/merge_requests/9.diff"
    }
}

Installation with #31 and migration steps from #25 worked for me going from D7 to D10.

However I got some errors with quiz_results_answers. I had 189 items in d7_quiz_result which were all migrated, but only 1516 items from the 1869 processed by quiz_results_answers were migrated. Perhaps the non migrated items are unfinished quizzes but there is nothing in migrate:messages that could help to debug. Also while rolling back quiz_results_answers , I got this error:

TypeError: Drupal\quiz\Entity\QuizResultAnswer::getQuizResult(): Return value must be of type Drupal\quiz\Entity\QuizResult, null returned in Drupal\quiz\Entity\QuizResultAnswer->getQuizResult() (line 26 of /path_to_site/web/modules/contrib/quiz/src/Entity/QuizResultAnswerEntityTrait.php) #0 /path_to_site/web/modules/contrib/quiz/src/Entity/QuizResultAnswer.php(162): Drupal\quiz\Entity\QuizResultAnswer->getQuizResult()

The other problem I got is with custom fields (I have a media_field in D7 quiz and question nodes) and usual drupal node fields like published y/n, author/date display, promoted, comments, etc or fields added by modules like metatag (essential for SEO), Any idea how to migrate these fields ? It is impossible to recreate all them as they are not accessible by "Re-use an existing field" and not available in the "Create a new field" options list. But perhaps this is not a migration problem but a limitation of the new quiz module concept. In such case, it is preferable to go the old way with quizzes and questions as nodes rather than trying to recreate a whole distinct entity.

Just a general comment. Is drupal quiz going to have a migration built in when updating from Drupal 7 to Drupal 8,9,10 ?

When is Drupal quiz 6.0 series expected to get out of alpha and beta testing?

Drupal 7 is end of life soon and it seems Drupal quiz has stalled. Is their an ETA for a production release?
