I am following the tutorial example from React.js Onboarding Using Intro.js however when I look at my page the tooltip is not popping up and my terminal is giving the following errors:

WARNING in ./node_modules/intro.js/intro.module.js
Module Warning (from ./node_modules/source-map-loader/dist/cjs.js):

Seems like warning caused by create-react-app and Webpack 5.x

To remove the warning simply add GENERATE_SOURCEMAP=false to your .env file, and then stop and start your project.

Also everything works fine for me on server.

  • https://github.com/usablica/intro.js/issues/1595. The issue is still present on the latest version even though it has been closed. I am not using CRA and webpack v5 but still getting the issue – Erick Jul 27 '22 at 12:43
