Thank. I think I understand what you mean. 
But I don't understand why such an error does not occur on the event onEnter ???

[LocomotiveScroll and ScrollTrigger - error when onLeaveBack and locoScroll.scrollTo]

I can resolve this problem like this (

onEnterBack: () => {);

                    locoScroll.off("scroll", ScrollTrigger.update);

                    locoScroll.scrollTo('.some_element', 0, 700);

                    locoScroll.on("scroll", ScrollTrigger.update);

                }

)
but I think than but I think that this no right (it's a crutch)

 

I use gsap v - 3.4.2

Help! I need scroll to 'some_element' when i leave some-section. For this I used event onLeaveBack. (

onLeaveBack: () => locoScroll.scrollTo('.some_element') ,

) and I get this error
(
