[Aerogear-users] IllegalArgumentException: argument cannot be null

[eduyayo]

Hi, 
theese last days I´ve found I cannot send push notificactions to GCM they
always fail and I donñt have a clue about the null argument that is
failing...

Any idea on this? Stacktrace follows:

2015-04-30 12:00:37,504 SEVERE
