ODK_Aggregate_v1.3.1 deployment on GAE

Hi,

I followed the instructions from http://opendatakit.org/use/aggregate/ and
I could upload the app to my GAE account. But when I go to my app

https://psi-myanmar.appspot.com/

it redirects and failed. I command I use to upload the app is

./appengine-java-sdk/bin/appcfg.sh --application=psi-myanmar update
ODKAggregate/

Any suggestions on this would be highly appreciated.

Thanks!
