I have 2 moodles on different servers.

Moodle A:  Version 4.3, This moodle was updated from version 3.9. It contains courses with new h5p activities from h5pactivity and old hvp activities from mod_hvp. 

Moodle B: Version 4.3.3+   with mod_hvp installed. This moodle was installed as moodle 4.3, not updated from older versions.

When I import a course from Moodle A in Moodle B, new h5p are playing well. Old hvp from mod_hvp throw the following error:

Call to a member function get_content() on bool Debug:
> Error code: generalexceptionmessage
> * line 258 of /mod/hvp/classes/file_storage.php: Error thrown
> * line 2537 of /mod/hvp/library/h5p.classes.php: call to mod_hvp\file_storage->cacheAssets()

> * line 44 of /mod/hvp/view.php: call to mod_hvp\view_assets->__construct()

This error seems to be the same error as reported here, some 4 years ago:

I am no moodle developer, so I cant fix this. Is there anybody who can solve this problem?

Best wishes
