ScrollTrigger.refresh() one of 30 times page reload get TypeError

[_Greg _]

Hi!

After 1-30 times of page reload (without update cache) i have Error 

On my app.js:13 code:

window.addEventListener('load', function(){
    gsap.registerPlugin(ScrollTrigger);
    ScrollTrigger.refresh();
})

 

I try to create codepen demo, but on codepen i did't see any errors  on console 

 

How can i catch or debug this type of error?

You shouldn't need this .refresh() there at all. ScrollTrigger automatically refreshes when needed.

 

If that's not the case, please provide a minimal demo that shows a case where refresh isn't being fired when it should.

Thank you!

I find with ScrollTrigger.getAll() one element from list of triggers, witch get that error. I will try to fix it. 

I try disable ScrollTrigger.refresh(); but trigger did't work with my code well (wrong place triggers on the page)

It's pretty hard for us to debug blindly. A demo would be much appreciated.

I had this exact same error occurring except I was not manually calling .refresh() instead it was being triggered automatically by ScrollTrigger but still throwing an error only on random screen refreshes as above. I updated to the latest version (3.5.1) and it seems to have fixed the issue.
