No, but other pages are using session. (Maybe 500 error page is using session. so this exception happend.) OK. I understood that don't use the session at Google App Engine as much as possible. If I use session, this exception will happen. I think the way I don't use session.
If you know the way I continue to use session, please tell me. Thank you.
