Published activity tracking app not working in the Vivoactive - Help please?

Hi all,

I just published this app here:
https://apps.garmin.com/en-US/apps/788e72db-d471-43be-8b90-4053d1e3a35e

It works fine in the simulator, but in my Vivoactive it simply shows an error screen.

IS THERE A WAY TO DEBUG THE APP IN THE VIVOACTIVE WATCH? :confused:

How can I find out what's wrong with the app?

The problem is documented here (with a screenshot):
https://bitbucket.org/ohtonen/vitalityactivitytracker/issue/5/does-not-work-at-all-in-the-actual-watch

The code is available here:
http://bitbucket.org/ohtonen/vitalityactivitytracker

How can I get this to work?

Please help? :)
