error/unknown_context_mapping when restoring a course with H5P activity

[TheRamSan]

Hi,
When attempting to restore a Moodle 3.9 course with H5P activity to a Moodle 3.8.3 I get "error/unknown_context_mapping"

Steps to reproduce the error:

Add an h5p activity to a moodle 3.9 course.
Backup the moodle 3.9 course.
Restore into a moodle 3.8.3 course.
The backup will fail with an error/unknown_context_mapping error.

What can be done?
Regards,
Ram

I can't import it - but I can manually upload it.

Hello,

I would like to see this bug fixed @fnoks

We ran into this error.

This happens (exclusively? I don't know) when the hvp activity backup has the main_library_id set to 0, meaning when an already broken hvp activity is backed up and restored.

Going back to the course on the old system that had the activity, we saw that the old activitiy worked.

We never backup hvp libraries because the backup process is slow as molasses.
What maybe happened back then was we backed up the course from the old Moodle server and then restored the course into the new Moodle server where the library in the requested Major.Minor was not installed yet.

mod_hvp looks for the library but doesn't react well to missing libraries when restoring. Meaning if the library isn't found, the main_library_id is just set to 0 (because that is "false")

Having a course with such a broken hvp activity leads to not being able to backup and restore that course anymore.
