Hello..
I am getting the below error in browser console when I integrated the modal loader code in my create-react -app.
SyntaxError: Unexpected token '<', ")
at GLTFLoader.parse (GLTFLoader.js:323:1)
at Object.onLoad (GLTFLoader.js:218:1)
at three.module.js:41500:1

Can you please help me resolve the same.
