NodeStunTest is not defined. App hangs at 90%

[zipzit]

I hate to state the obvious. I discovered this in the Chrome App Store. Thought it could be useful. The app hangs at 90%. You can't open chrome dev tools against it either. I did see the link to this repository, so I installed in local and ran via Extensions --> Developer Mode (check) and "load unpacked extension" I get the same response.. system hangs at 90% complete.

Error messages in console:

1. Failed to load resource: net::ERR_FILE_NOT_FOUND chrome-extension://dnldoacadgefgojgaogdbjgbooclcccn/node/bundle.js

2. extensions::uncaught_exception_handler:8 Error in response to socket.read: ReferenceError: NodeStunTest is not defined at ccd.StunTest.stunRequest_ (chrome-extension://dnldoacadgefgojgaogdbjgbooclcccn/js/stuntest.js:186:3)
