Failed to read the 'frame' property from 'Window'

[richburdon]

I have a simple Angular app that is loaded within an iframe within a Chrome Extension.

The app runs fine when loaded in an iframe outside of the extension, but when loaded via the unpacked extension, I get the following error:

Uncaught SecurityError: Failed to read the 'frame' property from 'Window': 
Blocked a frame with origin "chrome-extension://xxx" from accessing a frame with origin "https://google.com".  
The frame requesting access has a protocol of "chrome-extension", the frame being accessed has a protocol of "https". Protocols must match.

I'm starting to look into the Angular codebase, but can anyone suggest why the window.frame is being accessed (and if I can suppress this)?

This turns out to be a problem with systemjs not angular. Closed.
