Interactions are only showing in Designer, not in published site

Hey guys!!

I am facing a problem, where all ALMOST all my interactions (Lottie Files and Accordion Menu) do not work as in the Designer.

The full screen menu and inheriting interactions work.

I tried it in different browsers too, but I cannot find the problem. Could it be something with a Javascript that is not working?

Also it seems a bit laggy, but the .json files I used are only kilobytes big, so I cannot imagine that they would cause perfomance issues?

In the Browser console I found the following Error regarding to a property in .json:

Thanks for your help!!
