Heya!

 

There's no warning in that pen for me

 

That error means that you need to register your plugin though - e.g.
 

gsap.registerPlugin(ScrollTrigger)

gsap.registerPlugin(ScrollTrigger)

Hello , 

 If you are getting the error in the console, 

Make sure to add you js file below the cdn links.

<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.11.3/gsap.min.js"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.11.3/ScrollTrigger.min.js"></script>

<script src="/js/app.js"></script>

Something like this

@RohitSharma can you provide a minimal demo that clearly shows the problem? That CodePen works find and has no such errors. The only reason you'd be seeing that error message is if you forgot to call gsap.registerPlugin(ScrollTrigger) BEFORE you try using ScrollTrigger. 

 

If you're still having trouble, we'd be happy to take a look at a minimal demo that clearly shows the problem. We certainly want to help.
