Why on Angular 2 app page reload in IE I get multiple ..js.map files not found 404 errors?

Question

Ihave a Angular2 app that when I reload a page I get the following 404s..

I do not see these errors when debugging in Chrome - only IE11 an Edge (not tested on earlier IE versions or Safari etc)

I use WebPack for building.

Can someone point me in the right direction please?

Thanks.

It seems that most of your errors come from Observable and Subscription, it could be a compatibility problem due to ES6 expression. Angular 2 / 4 not working in IE11

Try to enable ES5 for IE instead ;)
