[4.0.0-beta.5] Cannot read property 'platforms' of undefined

[doender]

After updating to beta.5 I get the following error:

TypeError: Cannot read property 'platforms' of undefined
    at getPlatforms (platform.js:17)
    at isPlatform (platform.js:20)
    at Platform.push../node_modules/@ionic/angular/dist/providers/platform.js.Platform.is (platform.js:86)

Here's my environment:

Ionic:

   ionic (Ionic CLI)          : 4.1.1 (.nvm/versions/node/v10.6.0/lib/node_modules/ionic)
   Ionic Framework            : @ionic/angular 4.0.0-beta.5

   @ionic/ng-toolkit          : 1.0.7
   @ionic/schematics-angular  : 1.0.5

Until this is fixed and to be able to continue development I manually set the platforms in node_modules/@ionic/angular/dist/providers/platform.js for now:

export function getPlatforms(win) {
    return ['desktop'];
}
