Tile embed problem

[NativeCoder]

In my angularJS application, data in embeded tile (in iframe) is not getting rendered and always following error occurs.

'SCRIPT5: Access is denied.'

I am using same code which mentioned in GitHub example (https://github.com/Microsoft/PowerBI-CSharp/tree/master/samples/webforms/embed-a-tile-into-an-app). I am able to embed report but not the tile.

Kind request to provide solution.

Thanks
