Google App Engine Cron Jon failing with following error

[Khalid Razzaq]

Same code deployed on development system works fine but once deployed to production fails with following error:

Traceback (most recent call last): File "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 240, in Handle handler = _config_handle.add_wsgi_middleware(self._LoadHandler()) File "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 299, in _LoadHandler handler, path, err = LoadObject(self._handler) File "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 85, in LoadObject obj = __import__(path[0]) ImportError: No module named urlhandlers

Following is the URL Handler code

from utilities.logger import logThis, AEL_LEVEL_INFO, AEL_LEVEL_CRITICAL
from constants.constants import GAET_MASTERTASK_NAME, GAEQ_FOR_MASTERTASK
import sys

class QueueAMasterTask(webapp2.RequestHandler): 
    def get(self):
        try:
            dt =datetime.datetime.now()
            logThis(AEL_LEVEL_INFO, 'Master Task added to its Q at[%s]' %(dt))            
            task_name = GAET_MASTERTASK_NAME + str(datetime.datetime.now())
            task_name = re.sub('[^a-zA-Z0-9_-]', '_', task_name)
            taskqueue.add(queue_name=GAEQ_FOR_MASTERTASK,name=task_name)
            logThis(AEL_LEVEL_INFO, "OK-MASTER TASK ADD")
        except taskqueue.DuplicateTaskNameError:
            logThis(AEL_LEVEL_CRITICAL, "EXCEPTION on QueueAMasterTask-" +     traceback.format_exc())
        except:
            logThis(AEL_LEVEL_CRITICAL, "EXP on QueueAMasterTask-" +     traceback.format_exc())

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

There is one realted error I'm getting as well

/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py:85: ImportWarning: Not importing directory '/base/data/home/apps/s~apps-1149/1.391373453171312456/urlhandlers': missing __init__.py

Can it be because I'm importing some custom libraries?

[Christian F. Howes]

yes.  your custom libraries must not be quite right on the GAE path.  i recommend setting up a virtualenv for your local machine that does not have any system packages that GAE does not have, and that will help you make sure your included library paths are correct.
