A couple weeks back I filed #117 and it was fixed very quickly. At the time I was only running my project with iOS, when I dusted it off on android today I noticed that I'm getting a crash if I omit the 'scopes' parameter from my configuration on Android.
Attempt to invoke interface method 'int com.facebook.react.bridge.ReadableArray.size()' on a null object reference.
Sorry for not having tested this when I filed issue 117.
