[Uncaught TypeError: gsap_TweenMax__WEBPACK_IMPORTED_MODULE_4__.TimelineLite.to is not a function]

Thank you @GreenSock for your quick reply! It fixed the problem 

I was using react so I wrote like so: 

 

this.myTween = new TimelineMax();
this.myTween.to(this.myElement, .4, { opacity: 0.4, x: -80, ease: Power2.easeOut }).paused(true);

 

[Uncaught TypeError: gsap_TweenMax__WEBPACK_IMPORTED_MODULE_4__.TimelineLite.to is not a function]

(Hello this is my first forum post ever, please let me know if I can improve my post in any way  )

I've been loving using GSAP and recently started learning React and started utilizing GSAP with it.

So, when I use TweenMax, it works totally fine but when I try to use TimelineLite/TimelineMax, it gives me an error. 

 

Uncaught TypeError: gsap_TweenMax__WEBPACK_IMPORTED_MODULE_4__.TimelineLite.to is not a function

 

It's unclear for me what's causing this. (Wondering I might be doing something wrong with importing? or my react code?)

Below is the Comment component that I'm working on. 

 

import React, { Component } from 'react'
import axios from 'axios';
import TimeAgo from 'react-timeago'
//typical import
import {TweenMax, Power2, TimelineLite} from "gsap/TweenMax";
 
export default class Comment extends Component {

                content: this.props.comment.content,
                number: this.props.comment.number,
                time: this.props.comment.time
