JS file from Static Resource - Brandfolder JS (https://cdn.brandfolder.com/bf.min.js)
I have created JS file as static resource (BrandfolderJS) and using it in LWC.

LWC is added to App Builder Page/Home Page and trying to load, however it is going to catch block in loadScript method without any error. Error variable is undefined.

Can you please help?

Thank you,
