Thanks @1978milanbabic. Do you have a reproducible example so I can verify the bug?

Sorry, I work on a huge project and this was a MUST, ;) Luckily, found this solution..

This is a webpack issue for 'older' packages

Here is the solution that worked for me:
1.
npm i --save react-app-rewired
2.
In package.json "scripts" wherever you have 'react-scripts' -> replace with 'react-app-rewired'
like this:

"start": "react-app-rewired  start",
"build": "react-app-rewired build",
"test": "react-app-rewired test",
"eject": "react-app-rewired eject",

create 'config-overrides.js' file in root folder
4.
save config file with this content:

module.exports = function override(webpackConfig) {
  webpackConfig.module.rules.push({
    test: /\.mjs$/,
    include: /node_modules/,
    type: 'javascript/auto'
  });

  return webpackConfig;
};

Hi I'm having the same issue. How would I give you a reproducible example?
I'm on React 16.8.6.

@olupelumi can you create a CodeSandbox? See JavaScript or TypeScript
