@ivan @laura @jonathan I am happy i have found this issue before i posted a duplication.
We have taken the source code for Blockly games and did an extension of the activities on the maze game to add up the levels to 20.
I have now Zipped it as in the manual - https://kolibri-studio.readthedocs.io/en/latest/add_content.html#html5-applications.
The arrangement of the directories in the non zipped file are as shown -
and they work very well as shown
I then compress the contents as shown below
I then create a channel on Kolibri studio and upload the compressed folder then import it from my Kolibri.
When I click to open the channel I see a nice icon-
I hoped it would run the index file but it doesn’t seem to run and gives the error below.
Any ideas of what i could potentially be doing wrong?
