Content development tutorial issue and comment functionality

Ok I have a few issues with H5P for beginners. I wanted to post the comment in relation to this tutorial https://h5p.org/using-other-libraries but for some reason I cannot login to comment there, only here. Can someone look into why that is?

There seems to be issues with several of the beginner files and tutorials. I tried uploading the attached h5p in the above link on two lms'es without it working. This is the error message:

• A valid content folder is missing
• A valid main h5p.json file is missing
• Notice: Trying to access array offset on value of type null in h5p_validate() (line 555 of /home/akidsxbv/h5.jfcg.no/sites/all/modules/h5p/h5p.module).
• Warning: Invalid argument supplied for foreach() in h5p_validate() (line 555 of /home/akidsxbv/h5.jfcg.no/sites/all/modules/h5p/h5p.module).
• The uploaded file was not a valid H5P package

It would be very helpful if you could provide working h5p's along with the tutorials? Thanks Jorgen
