web-animations-js published 2.3.2 which includes the fix for this error on angular 8

The problem is coming from web-animations-js.

Since Angular 6, it is no longer needed:

We’ve updated our implementation of Animations to no longer need the web animations polyfill. This means that you can remove this polyfill from your application and save approximately 47KB of bundle size, while increasing animations performance in Safari at the same time.

https://angular.io/guide/browser-support#enabling-polyfills

Remove the import from polyfills.ts:

import 'web-animations-js';

And remove "web-animations-js" from your package.json:

"web-animations-js": "^2.3.1"

This solved my problem.

The current polyfills.ts from Angular does not contain it anymore: https://github.com/angular/angular/blob/master/aio/src/polyfills.ts

Angular 8 has the breaking changes with the versions of typescript and Node

typescript version should be 3.4

Node version should be 12 or later
