Python Google App Engine Cron Job/Scheduled task Not Working

Question

I am creating this cron job to get twitter feeds and store it in datastore. I tried everything, but my cronjob is not working. I read following articles/tutorials and some stackoverflow questions, but I can't solve this out.

https://developers.google.com/appengine/docs/python/config/cron

http://cloudartisan.com/posts/2010-06-02-scheduled-tasks-with-google-app-engine-python/

Here is my code

This is cron.ymal

cron:
- description : capture twitter feed 
  url : /twittertask
  schedule: every 1 minutes
  target: version-2

This is the class I need to do the job.

import webapp2
from google.appengine.ext import db

class Twitt(db.Model):
    created_at = db.IntegerProperty(required = True)
    id = db.StringProperty(required = True)
    text = db.StringProperty(required = True)

class TwitterTask(webapp2.RequestHandler):

    def get(self):
        url = "https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=BeijingAir&count=10"

        json_string = urllib2.urlopen(url).read()

        data = json.loads(json_string)

        for item in data:
            created_at_item = item['created_at']
            text_item = item['text']
            id_item = item['id']

            e = Twitt(id = created_at_item, text = text_item, id = id_item)
            e.put()

        self.response.out.write('Hello prueba!')

This is app.ymal

application: cronjob
version: 1
runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /.*
  script: index.app

- url: /twittertask
  script: twittertask.app

This is index.py

import webapp2

class MainPage(webapp2.RequestHandler):
  def get(self):
      self.response.headers['Content-Type'] = 'text/plain'
      self.response.write('Hello, Check Admin')

app = webapp2.WSGIApplication([('/', MainPage)],
                              debug=True)

def main():

    run_wsgi_app(application)

if __name__ == "__main__":
    main()

Well, I can't find where is the error. I tested on my dev server. I didn't upload it to google app engine.

The problem is in your app.yaml. URLs are matched from top to bottom, but your first handler matches all URLs. Move the twittertask entry so it's first under handlers.
