Ionic View: "Copying cordova files" error

At the moment I’m getting in the new Ionic View app (iOS) following error:

There was an error copying cordova files

I also checked the Ionic View android app, and there I’m getting a 404 file not found error.
I already tried to remove the android and ios platform and added them again. Both platforms I can build sucessfully.

The specifications are like this:

<engine name="ios" spec="^4.4.0" />
<engine name="android" spec="~6.4.0" />

Where and how exactly are you getting this error? Can you provide a screenshot?

I attached the print screen of the error. When I choose the right channel I can see the instructions of Ionic, but before the splash screen of my app appears I can see this error message and get send to the channel view right away.

Interesting. I would advice you to create a new project with ionic start and try the same with this project. Does it work?

Something I already tried. When I setup a blank new app and view it in the Ionic View app, then it’s working.

Also with a ionic-v1 app?
If yes, compare those two project.
