Hi John,
Tracking down the exact exception is a bit tricky in this case as in this
stack trace apiproxy_rpc re-raises whatever exception is sent it's way. I
would guess that the particular Error class is originating from
google/appengine/api/datastore_errors.py but to configm you could catch the
exception e and log or display type(e).
Cheers,
Jeff
