[aerogear-dev] Problem with Push notification chrome-app

Hello, I'm trying to follow this tutorial: https://github.com/lholmquist/aerogear.org/tree/AGPUSH-549/docs/guides/ae... Because I want to do an app that is able to receive push notifications. But I'm having problems and seems that are coming from the AeroGear.js. But I'm not sure. I was debugging my application and it's returning this: Error in response to pushMessaging.getChannelId: TypeError: Object #<Object> has no method 'UnifiedPushClient' anyone at anytime got this error? and know how to solve it? this error comes from the "main.js" file on line 14 -> https://github.com/lholmquist/aerogear.org/blob/AGPUSH-549/docs/guides/ae... Thank you :) -- Vasco Amaral
