Hi This has been an intermittent problem for us as well. We haven't been able to identify a fix.

I'm using the same Moodle version and students are reporting a similar issue where grades are not recorded in the grade book for the 'course presentation' H5P activity on Moodle.

What is common, is the problem regularly happens with the same students repeatedly.

I've also noticed a script is sometimes blocked from running when using Edge browser causing the course presentation container not to be fully responsive and the height is too small to see slide content. The only fix that seems to work is to clear local clients browser cache.

it would help greatly in solving this if you're able to find a way to reproduce the problem consistently and steps to achieve this.

Has anyone found a resolution for this? I am having the same issue. Moodle 3.11, PHP 7.3.31, everything seems to be working great, but as stated above, interactive videos do not show as completed for the student and nothing is recorded to the gradebook. I can provide logs, screenshots. or whatever will help solve this.

UPDATE : Found a solution in another discussion thread. Updating interactive video libraries to 1.22.14 solved the problem!

Bonjour Hi, we have the same problem here. Interactive videos do not show as completed neither the scores available to the teacher. Is it a H5P problem or a Moodle problem? Looking at the URL of this thread, I notice though that it seems linked to the moodle plugin HVP. My problem is related to H5P natively integrated in Moodle, not the old moodle plugin.

I have also found this particular problem using a number of different H5P activities and I thankfully have found what I think is the core issue and come up with a fix that so far seems to be working 100%.

The issue stems from H5P performing 2 AJAX calls simultaneously on the xAPI Completed event. 1 of these AJAX calls will create the completion record for the course, while the other updates grades. If the grade update happens first it fails as there is no completion record, hence users can simply repeat the activity to then gain a grade. This race condition is the reason the issue is intermittent, as it is wholly dependant on in which order the AJAX calls are made and processed.

The H5P activity that is built directly into Moodle from 3.8 onwards doesn't have this issue as it only triggers one AJAX call that both creates the completion record and updates the grades.
