Thanks so much for the response, In typical fashion I figured out my issue after posting the question. I was querying h1, and p at the same time and React did not like that at all. I'm sure there's a specific reason I can't do that, but for now it's working so that's good enough for me. As for yPercent - thanks for the recommendation, definitely want to develop good habits when working with GSAP so will definitely change.

I've been a long time user of GSAP and have used the SplitText plugin on many projects. I've been learning React and more specifically the Gatsby library and have run into an issue I cannot solve. I setup this SplitText in my Gatsby project and it worked fine - then all of a sudden today it broke giving me a Type Error. I've downloaded the most recent GSAP library and Gatsby/ React is up to date as well. TypeError: null is not an object (evaluating 'parent.insertBefore') (I know this code below is partial - I ripped out a lot of excess code) import React, { Component } from "react" import { TweenMax } from "gsap/TweenMax"; import SplitText from "../utils/gsap/SplitText" export default class IndexPage extends Component { componentDidMount() { const split = new SplitText( 'h1, p', { type: "lines", linesClass: "ts-line" } ) TweenMax.staggerFrom( '.ts-line', 1, { y: "125%", opacity: 0, }, 0.25, ); } render() { return ( <Layout> <h1>Heading Text</h1> <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
