My react-app does not render

Hello,
My react-app does not render in the browser when I access it from an app server, so I hope to get some help with it.

Below is the info I hope is needed to understand the structure.

I run a weblogic server 14.1
I deploy a ear with several war-files
Inside the ear I got a angular-app and a react-app in individual war-files.
I build the wars and the ear with maven.
For the ear I add the wars like:
                        <webModule>
                            <groupId>weblogic-ejb-project</groupId>
                            <artifactId>weblogic-angular-client</artifactId>
                            <bundleFileName>weblogic-angular-client.war</bundleFileName>
                            <contextRoot>angular</contextRoot>
                        </webModule>
                        <webModule>
                            <groupId>weblogic-ejb-project</groupId>
                            <artifactId>weblogic-react-client</artifactId>
                            <bundleFileName>weblogic-react-client.war</bundleFileName>
                            <contextRoot>react</contextRoot>
                        </webModule>


The angular-app renders when I access it from the browser (http://127.0.1.1:7001/weblogic-angular-client/)
But not the react-app (http://127.0.1.1:7001/weblogic-react-client/), just a blank page. How ever the view-source shows the content from index.html like:

<!doctype html><html lang="en"><head><meta charset="utf-8"/><link rel="icon" href="/favicon.ico"/><meta name="viewport" content="width=device-width,initial-scale=1"/><meta name="theme-color" content="#000000"/><meta name="description" content="Web site created using create-react-app"/><link rel="apple-touch-icon" href="/logo192.png"/><link rel="manifest" href="/manifest.json"/><title>React App</title><script defer="defer" src="/static/js/main.a083f8ba.js"></script><link href="/static/css/main.073c9b0a.css" rel="stylesheet"></head><body><noscript>You need to enable JavaScript to run this app.</noscript><div id="root"></div></body></html>

...so it looks like the react-app is present with the content from index.html

Do you guys see anything missing for the react-app?

Best regards
Fredrik

PS1 it does render if i run npm start and access it from localhost:3000, so it does work that way.
PS2 I have also checked that main.a083f8ba.js is in the correct folder and can be accessed from http://127.0.1.1:7001/weblogic-react-client/static/js/main.a083f8ba.js
PS3 I have tried with the same result from Firefox, Chromium on Linux and Chrome from an old Android-phone

A picture of the ear and the war files might be found here:

Hmm I see a message in the console: Loading failed for the <script> with source “http://127.0.1.1:7001/static/js/main.a083f8ba.js”.

looks like this solved it in my package.json
{
  "name": "react-client",
  "version": "0.1.0",
  "private": true,
  "homepage": "/weblogic-react-client",

I read it as you solved it yourself. If so you should mark #2 as an answer.
