Getting Uncaught reference error on some of the pages

[premhunt]

Getting error on some of the websites built with magento.
ex- https://shop.landrover.com/
After adding <script src="https://cdn.jsdelivr.net/npm/jsframe.js/lib/jsframe.min.js"></script>.
returned - 200, so my jsframe.min.js got loaded but
If I am doing
jsFrame = new JSFrame();

It gives error -
Uncaught ReferenceError: JSFrame is not defined
at :1:15
