ScrollSmoother Uncaught TypeError: Cannot read properties of undefined (reading '_getVelocityProp')

Included the min file inside the folder, and registered the plugin, but caught the error:

ScrollSmoother Uncaught TypeError: Cannot read properties of undefined (reading '_getVelocityProp')

gsap.registerPlugin(ScrollTrigger, ScrollSmoother)

 

let smoother = ScrollSmoother.create({

wrapper:"#smooth-wrapper",

content: "#smooth-content",

smooth: 2, // seconds it takes to "catch up" to native scroll position

smoothTouch: 0.1,

effects: true // look for data-speed and data-lag attributes on elements and animate accordingly

})

Issue solved, wrong version of GSAP
