interactive book

In 2022, I created a relatively complex and multi-part course as an ‘interactive book’ that I would now like to offer again. When updating some content, I received the following error message when saving: ‘count(): Argument #1 ($value) must be of type Countable|array, null given’.

Please please please can someone answer my question.. .how do I get the libraries for game map and interactive book for drupal module.  They do not show up as available, and attempting to upload a sample of each fails due to a missing library for each.

pleae answer.

Hello,

when the students send a report at the end of an interactive books, I can see only the score, not the specific answers. Is that normal?

Best regards

Berti
