Hi Nick
Even when I replace my grabber with the below, the cron still fails.
By this I mean that when I look in the dashboard and click the cron
jobs, it says that the cron has failed.
I don't really understand why. I think my problem is somewhere
"webapp.WSGIApplication" call, and the app.yaml/ cron.yaml
As I say its such a basic example I would of thought it would run? Or
am I deluded?
Cheers
grabber.py
**********
from google.appengine.api import users
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
class grabber(webapp.RequestHandler):
def get(self):
x = "hello"
application = webapp.WSGIApplication(
[('/', 'grabber')],
debug=True)
def main():
run_wsgi_app(application)
if __name__ == "__main__":
main()
