Failed to parse source map errors when running the code

When running application with CRA / react-scripts 5.0 getting a bunch of errors like this:

WARNING in ./node_modules/react-bootstrap-sweetalert/dist/components/Buttons.js

I can confirm that using "react-scripts": "^4.0.3" makes this issue go away.

This seems to be due to upgrading to webpack 5. As a workaround you can ignore these warnings by adding env var GENERATE_SOURCEMAP to false See here https://github.com/facebook/create-react-app/discussions/11767

By setting GENERATE_SOURCEMAPS to false, you will make debugging your app much harder. It's being fixed in this PR
