I have an app built with create-react-app. When i run the build command i get this error:

I also attached the debug log 2018-01-14T15_07_27_354Z-debug.log

Can anyone tell me how i can fix this?

@newyork-anthonyng I got it working with step 3, however, i feel like this is a bug with this package and attempt to fix it should be made.

@borisyordanov this should be fixed. We just ran into issue with this in IE 11 on our app. @MelkorNemesis’s pull request should be merged IMHO.
