OpenId : unable to retrieve record with openid User

[Roberto]

Hi all,

I have a serious problem with an application using OpenId
autentication.

I tested the app using using blogger.com as an openid provider and
stored the User object in the Datastore, in a UserProfile table.
Now it is not possible to retrieve the entity containing that User,
raising UserNotFoundError.

Even the remote Datastore Viewer crashes with the following message
when querying the entity:
Server Error
A server error has occurred.

Any help is appreciated.

Thanks
Roberto

Sorry for the repost, but I am totally stuck.
There is no way of removing the corrupted entity.
App Id: test-pappa-mi
Entity: Commissario (corrupted entity should be the last created of
its kind)

this is the stack trace:

Well, I was able to solve it by myself: did a SELECT __key__ query,
fetched the last entity and deleted it.

My undertanding is that the problem was generated by creating and
storing a User object created with a federated_identity with no email
address (blogger.com, in that specific case).
The application must verify that this information is passed by the
federated_provider and if not, ask the user to provide it via a web
form or do not attempt to store the object.

Thanks
Roberto

I got a similar issue.

Saving an instance "put()" of an object with a UserProperty referring
to a users.user that is a federated_identity causes a corruption of
the instance. accessing the object after the put will result in the
following exception:

File "/base/python_runtime/python_lib/versions/1/google/appengine/api/
users.py" in __init__
104. raise UserNotFoundError

This is totally weird since I'm not even updating that property.
