Hello there,
I am trying out the Channel API with my own project and the Google
demo app Dance Dance Robot. In both cases I get ApplicationError 2
when trying to push a message. There is no doc but all libraries are
available in the lastest GAE release. Here is the error:
com.google.appengine.api.channel.ChannelFailureException: An
unexpected error occurred.
Caused by: com.google.apphosting.api.ApiProxy$ApplicationException:
ApplicationError: 2:
See trace below.
What is ApplicationError2, how to fix it?
Any help / pointer would be appreciated.
Thanks.
Daniel
