error obtained
AssertionError: Headers already set!
This all comes from webapp2. You should never see assertion error.
Report to authors or ask on webapp2 mailing list if there is one.
Status: 500 Internal Server Error
Content-Type: text/plain
Content-Length: 59
You should have made subject line something like
"Webapp2: AssertionError"
as only someone familiar with webapp2 could give you any help.
