TypeError: Cannot add property _gsap, object is not extensible

Recommended Posts

Hi there,


I have searched all over the internet for hours without any luck.

My guess is it has something to do with the gsap.registerPlugin(ScrollTrigger)

I have attached some screenshots. I would appreciate any help.

Thank you!

Unfortunately no luck. I studied the codes, refactor my code and did all sort of things.


Thanks though!
