Deploying a react app using github pages project wont render

Question

I'm trying to deploy an App to on GitHub using GitHub pages but for some reason It wont render on the page but when I build it locally it works fine. I tried inspecting it but all I can see is this error message:

Loading failed for the <script> with source “https://princenwaonicha.github.io/static/js/main.cfded94d.js”. The link is here. https://princenwaonicha.github.io/CatPals/

I followed the tutorial on uploading it to github. One thing to note is I am using a custom scrollbar module that needed to be installed with --legacy-deps. But that was the only way to install github pages.
