Tincan not loading on LMS JS-error

Hi!

I have just bulit a e-learning course in Storyline 360 and our webbdeveloper has tried to put it on our LMS but gets an error and course does not load.

It works as scorm 1.2 but we need tin can version so it works with the trackning system we have on the LMS.  

I have tested the course on Scorm Cloud and it works just fine. 

Our webdeveloper is getting this message "cannot read property "asVersion" of null. Please see attached image for complete JS-error message.

Possible issues could be:

1. only works on https 
2. Path related: may be there might be any path hard coded.
3. Domain restriction. May be from inside tincan there might be any JS library which doesn’t allow our local domain
4. Might be React Library version issue

Does anyone have any suggestions?
