Timeline Exception: Call to a member function get_content() on boolean

Hey there,

I tried to add my first H5P timeline to a course in Moodle. I set up two dates, images, captions, etc. H5P saved it w/o any error message and I can see the activity in my course. When I (or sb else) try to open it I get 'Exception - Call to a member function get_content() on boolean' error message. I deleted and re-created the activity with no luck.

Additionally on the page with the Exception I also have a js console error msg: ReferenceError: H5PIntegration is not defined @ h5p.js:987:7.

We have the latest Moodle (3.7.2+?) on Debian 3.16.39, Apache 2.4.25, php 7.1.30, PostgreSQL 9.6.13, with fresh H5P modules. All the other H5P modules (a lot) we use work perfectly.

Exception error when opening Timelime content type

When I re-open the timeline in the editor, everything looks fine: I can edit and save but I can't save and review changes - > Exception...

Error code: generalexceptionmessage

Hope it helps.

Hey guys,

It would be great to use this feature. Is there any chance to get a correction for this error?

Hi hellsing,

Would you mind providing sample content. I tried reproducing the issue on a similar setup but I am unable to do so.


Sorry but I can't. We are on intranet. Also I can't open the content for a view so I can't export it into an h5p file.

Is it possible to 'reset' a H5P module? When I installed H5P there were some modules hat had to be downloaded by clicking a 'Get it' button. Can I somehow set a module to that state?

It's so strange all the other modules work perfectly.

Hi hellsing,

I'm not really sure if it is possible in Moodle, but it sounds like a viable solution. I hope that someone else in the community has some suggestion.
