Enable OS Bar V4 in Angular Application

[FedericoPeccia]

I am trying to implement the OS Bar V4 in my application made using Angular. I followed the guidelines in the documentation and also based the changes I had to make to my app from this great example on how to add the OS Bar V4 in an Angular application.

The error I am getting when I load the app in my browser (Chrome) is the following:

main.d34aa40ff1c11c0944d3.js:1 ERROR Error: Expecting function got: undefined
    at t.wrap (polyfills.20d0bb3b90b253b298ff.js:1)

Any ideas?

Did the previous version of the mdsp bar work earlier in the same app or is this the first time the bar is integrated?

Actually, it's the first time I integrate the OS Bar to this app.

This is happeninng because of the problem with zone.js version larger than 0.8.26 in angular7 apps.

A current workaround is to revert your zone.js version to 0.8.26

npm install zone.js@0.8.26 --save

After that the OSBar should work again.

Thanks @darthsn0wcat ! Worked like a charm!
