'allow-same-origin' flag?

[Bruce Davidson]

I'm trying to create an extension that uses the WebAudio api. My app works when in a separate web page, but when I try to run it as an extension, I get this error:

Uncaught SecurityError: Failed to read the 'serviceWorker' property from 'Navigator': Service worker is disabled because the context is sandboxed and lacks the 'allow-same-origin' flag.

Where/how do I set this 'allow-same-origin' flag? Is there a complete list of all the keys/flags in the manifest that references this?

I'm afraid that I don't quite follow your question. Could you share a demo extension that illustrates the issue you're having?

A sandboxed context is created when you do this:

<iframe src="..." sandbox></iframe>

If that's what you are doing, then you can add the "allow-same-origin" flag to the sandbox attribute, like this:

<iframe src="..." sandbox="allow-same-origin"></iframe>
