Sample XML Deploy failed with status 400

[#1]

Hi I am trying out the tutorial at

http://apigee.com/docs/api-services/tutorials/part-3-use-xml-samples-and-deployment-tools . At step 2.4 my deployment fails with status 400.

Here is the log:

Enter your password for the Apigee Enterprise organization zzz, followed by[ENTER]:

Imported new proxy version 3
Deploy failed with status 400:

If 'State: deployed', then your API Proxy is ready to be invoked.
Run 'invoke.sh'

I can manually deploy the proxy from the Management UI, but I am not able to figure out what is going wrong with me running the scripts.

Please help.
