Bugs in content types

Hi, I downloaded Lumi 1.0.0 desktop app and installed it on Windows 11.
I tried to install the Interactive Book activity example from the Lumi site, but failed to do so. The error happens when opening the downloaded file.  

Message was...
Error: Could not open h5P

Here is the link to the acivity. 
https://h5p.org/content-types/interactive-book

I managed to find another example from another site and that loaded fine. 


Thanks.

Hi!

This is a problem that you should report to Lumi.

You might have installed an older version < 1.0.0 of Lumi Desktop which does not support content types that require the latest version of H5P. As of Lumi Desktop 1.0.0 that's fixed, but the Microsoft store still might serve the old version of Lumi Desktop. Again: Something that Lumi must fix. And you say you have 1.0.0.

Another cause might be that Lumi Desktop does not upload the file, because the file does not contain all the libraries that the content needs. The export function on H5P.org has not been including those for half a year or so to safe storage. The files are not mandatory, but Lumi Desktop might interpret the H5P specification that way. Once more: Lumi would need to take action.

Best,

Oliver
