Importing anything from @angular/cdk in Cypress tests breaks the build with Angular 13

Question

Since updating to Angular 13, my Cypress tests that are importing from @angular/cdk (mostly for using test harnesses on Angular material) fail to compile with the following error:

Error: Webpack Compilation Error

Any idea how to solve this? I assume it has something to do with the changes in the Angular Package Format..

Is it reproducable on a clean newly created Angular 13 project? Can you please create a small github repository that proves that? — yurzui, Nov 30 '21 at 20:15

In the meanwhile, we found a workaround:

const webpackPreprocessor = require('@cypress/webpack-batteries-included-preprocessor')

module.exports = (on) => {
  on('file:preprocessor', webpackPreprocessor({
    typescript: require.resolve('typescript')
  }))
}
