Uncaught (in promise): Event: {\“isTrusted\”:true}

Apr 28 2019 11:30 PM

My Angular 5 application is getting this error in the polyfills bundle on some browsers. Since it does not happen on my own browser, I can't reproduce it or find out anything more about it - I'm just posting the errors that happen on the front-end -.

Any idea where it might be coming from?
