Upgraded Unity Version from 2019 to 2021, Upgraded react-unity, getting unityContext undefined

[Squizyton]

Hello,

My team recently upgraded our unity from 2019.1 -> 2021.2.

Which meant I had to change reacts version to the newest one due to Unity changing how it builds webgl.

I'm currently using react-unity-webgl@8.x as my version.

I've been following the examples in the Documentation however, if I do npm start I get a unityContext is undefined.

If I run a build through npm build, i just get a e is undefined

The problem I think is the fact that we are getting builds from the cloud, however I entered the url (that is redacted here) fully and I still got the error.

Any solutions to this?

`
import React from 'react';
import Unity, { UnityContext } from "react-unity-webgl";
import { ProgressIndicator } from 'office-ui-fabric-react/lib/ProgressIndicator';
import './TevolveGame.css';

class TevolveGame extends React.Component {
constructor(props) {
super(props)

this.state = {
  progression: 0,
  loading: true
}


  const unityContext = new UnityContext({
  loaderUrl: "${props.build}/Build/Tevolve.loader.js",
  dataUrl: "${props.build}/Build/Tevolve.data",
  frameworkUrl: "${props.build}/Build/Tevolve.framework.js",
  codeUrl: "${props.build}/Build/Tevolve.wasm",
  streamingAssetsUrl: "streamingassets",
});

const App = () => {
  return <Unity unityContext={unityContext} />; // <-- unityContext
};

Never mind I figured it out.

I apparently had a render function hidden that was erroring out.
