An unhandled exception occurred: Class extends value undefined is not a constructor or null #174

Trying to run ng build of my app and I am getting the "An unhandled exception occurred: Class extends value undefined is not a constructor or null" error. Any help would be greatly appreciated. Using latest of webpack-subresource-integrity, latest @angular-devkit\build-angular & latest Typescript.

Could you send over your package-lock.json or yarn.lock file? And your package.json would be good to see as well.

I have attached those files in a zip. Thank you for your help! files.zip

No problem. Your use of storybook forces Webpack to version 4:

$ grep version node_modules/webpack/package.json
  "version": "4.44.2",

That version is incompatible with a number of other dependencies you've installed, including the version of our plugin that you're using (5.1.0).

To fix this, remove storybook or enable Webpack 5 support for storybook, then ensure that you're using Webpack 5.

I'll leave this ticket open as a reminder to myself that we should probably print a more helpful error message in this case.

It looks like I need to update some other libraries as well but I am no longer running into the original error after enabling Webpack 5 for storybook. Thank you again for your help!

Sorry, you said you were going to leave it open.
