Hello,
I'm discovering moodle and my deployment context is a bit complicated. I'm deploying in an air-gap environment (without any internet connection).
I have build the h5p interactive book content type from the github repo and I have uploaded into moodle:

If I try to use it I have a problem with the drop down into the item/page. This drow down is empty.

I can't understand why.
My moodle version is Version 4.5.4 (Build: 20250414). This setup has never been connected to internet. The cron job to download the h5p content types has been disabled because it can't work in my environment.
Any idea please ?
