Google App Engine - Endpoints Failure

I'm trying to deploy a gae project with endpoints but it's giving me errors that's should be happening.
I Don't Think there is anything wrong with my code but i keep getting this error when trying to deploy:
There is a /_ah/spi handler configured, but no Google Cloud Endpoints service was found in the app
my app.yaml :
application: app-id
version: 1
runtime: python27
api_version: 1
threadsafe: true
# --- Handlers
handlers:
- url: /favicon\.ico
static_files: favicon.ico
upload: favicon\.ico
- url: .*
script: main.app
secure: always
- url: /js
static_dir: static/js
- url: /img
static_dir: static/img
- url: /css
static_dir: static/bootstrap/css
- url: /fonts
static_dir: static/fonts
- url: /partials
static_dir: static/partials

script: game.api

# --- Libraries
libraries:
- name: webapp2
version: "2.5.2"
- name: pycrypto
version: latest
- name: endpoints
version: latest
- name: jinja2
version: latest
and my game.py :
from datetime import datetime
import endpoints
from protorpc import messages
from protorpc import message_types
from protorpc import remote
from google.appengine.api import memcache
from google.appengine.api import taskqueue
from google.appengine.ext import ndb
# --- Setup Code
WEB_CLIENT_ID = 'app-id'
# --- Classes
class Hello(messages.Message):
"""String that stores a message."""
greeting = messages.StringField(1)
class TestOne(messages.Message):
''' TestOne message '''
msg = messages.StringField(1)
# --- API & Endpoints
#endpoints.api(name='whoamigame', version='v1')
class WhoAmIGameApi(remote.Service):
#endpoints.method(message_types.VoidMessage, TestOne, path='testone', http_method='GET', name='testonemethod')
def testOneM(self, req):
testOneMsgReturn = TestOne(msg='Test One...')
return testOneMsgReturn
# --- API
api = endpoints.api_server([WhoAmIGameApi])
Every time i try to deploy it, the endpoints fail. i'm not sure how to fix this issue. the code and syntax is perfect to me. everything is defined. the sdk fails every time.

Google App Engine Task Queue error

I'm developing a matchmaking system with gae and python. I was finding a consistent system for automatic matchmaking, and I found the task queue. I implemented a cron job to run every 10 minutes to add a queue. However I'm getting the following error:
When running /queue_generator:
Traceback (most recent call last):
File"/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 267, in Handle
result = handler(dict(self._environ), self._StartResponse)
TypeError: 'module' object is not callable
The code that I have is:
(SessionID is just a db model)
queue_generator.py
import webapp2, time
from main import SessionID
from google.appengine.api import taskqueue
from google.appengine.ext import db
class Game(db.Model):
Users = db.ListProperty(str)
Score = db.IntegerProperty()
Turn = db.StringProperty()
class MainHandler(webapp2.RequestHandler):
def get(self):
taskqueue.add(url='/matchcreator',params={"id":str(time.time())})
class Gamegenerator(webapp2.RequestHandler):
def get(self):
while True:
q = Queue.get()
if len(q.queue) >= 4:
sids = []
for i in range(0,3):
sids.append(q.queue[i])
q.queue.remove(i)
q.put()
return self.response.set_status(204)
def post(self):
while True:
q = Queue.get()
if len(q.queue) >= 4:
sids = []
for i in range(0,3):
sids.append(q.queue[i])
q.queue.remove(i)
q.put()
return self.response.set_status(204)
app = webapp2.WSGIApplication([
('/queue_generator', MainHandler),
("/matchcreator",Gamegenerator)
], debug=True)
Why is this error occuring?
Edit
app.yaml
application: brobbinsgame
version: 1
runtime: python27
api_version: 1
threadsafe: yes
handlers:
- url: /favicon\.ico
static_files: favicon.ico
upload: favicon\.ico
- url: /css
static_dir: css
- url: /home.css
static_files: style.css

For every path except "/queue_generator, you have correctly referenced the app object. But for that one path, you reference the module directly. You need to define it in exactly the same way:
- url: /queue_generator
script: queue_generator.app
login: admin
Also notice that there is no way to get to "/matchcreator": "/queue_generator" is the only URL that will be routed to that file. You need to either expose "/matchcreator" in app.yaml as well, or do the more usual thing which is to route all the paths to a main app which imports all the handlers and defines the specific routing there.

This error is occurring because you are calling a Module instead of a Class.. the call should be : Module.Class.Method()

GAE/Python ImportError only on the deployed version

Hi everyone I'm struggling with AppEngine, I made my webapp on the development server, everything worked fine but once I deploy it gives me an ImportError.
My main directory is as follows:
-/
-Several
-Folders
-...
*admin.py
*app.yaml
*db_objects.py
*index.yaml
*img_getter.py
*keys.py

When I go to myaddress.appengine.com/admin it gives me this error:

This is the beginning of admin.py:

And this is the beginning of the img_getter.py file:
import gdata.photos.service
import gdata.media
import gdata.geo
def foo(variable):
...
def bar(variable):
...
#functions to get images from the google picassa service
The thing is I've been developing this webapp on the developer server and it's been working like a charm, I've even cleared the datastore and tried on several computers and it's still working, but when I try to test it on Google servers I'm finding this error.
I haven't define any reference on the app.yaml file as I think it's not necesary because it's not a library depending from google python API, am I wrong?
Does anybody know what the problem is?
Thank you very much :)

You might need to import it as a package.
https://docs.python.org/2/tutorial/modules.html#packages
Create a folder called 'test' (or whatever you want) for img_getter.py and put it in there
Add a file called __init__.py and save it in the folder you put img getting in. This file can be empty
call the import as
import test.img_getter

Requested url not found on server error

I made a website which I am temporarily hosting in app engine. I am able to navigate through the pages when I open the HTML files on my computer. It only fails when I head to http://www.alshafarconstruction.appspot.com/index.html.
Error Message:
Error: Not Found
The requested URL /contact.html was not found on this server
app.yaml:
application: alshafarnew

main.py:
from google.appengine.ext import webapp

class IndexHandler(webapp.RequestHandler):
def get(self):
if self.request.url.endswith('/'):
path = '%sindex.html'%self.request.url
self.redirect(path)
def post(self):
self.get()
application = webapp.WSGIApplication([('/.*', IndexHandler)], debug=True)
def main():
run_wsgi_app(application)
if __name__ == "__main__":
main()
I've checked the dashboard and find that the HTML files are there. I am new to website deployment and design. Can anyone suggest possible errors? I have already visited many sites for a solution.

The documentation hints that static and application files are uploaded separately, so while the files may be there, it might be that they're being uploaded in the application-files part.
You currently have an upload directive telling it to only upload index.html:
- url: /(.*\.html)
static_files: \1
upload: index.html
(actually, it's a regular expression, so it would also upload, for example index#html if it existed)
This suggests that you might want to make that regular expression match all HTML files:
- url: /(.*\.html)
static_files: \1
upload: .*\.html

Google App Engine Error (The requested URL / was not found on this server)

I am trying to create a simple web application that says Hello Udacity and upload it to Google App Engine, but I keep on getting a bunch of errors.
Error message from Google App Engine:
11:57 PM Host: appengine.google.com
Error parsing yaml file:
Unable to assign value 'udacityassignment2' to attribute 'url':
Value 'udacityassignment2' for url does not match expression '^(?:(?!\^)/.*|\..*|(\(.).*(?!\$).)$'
in "C:\Users\Wealthy\Desktop\ambhelloworld\udacityassignment2\app.yaml", line 12, column 8

You can close this window now.
app.yaml:
application: udacityassignment2
version: 1
runtime: python27
api_version: 1
threadsafe: yes
handlers:
- url: /favicon\.ico
static_files: favicon.ico
upload: favicon\.ico
- url: udacityassignment2
script: main.app
libraries:
- name: webapp2
version: "2.5.2"
main.py:
import webapp2
class MainHandler(webapp2.RequestHandler):
def get(self):
self.response.write('Hello Udacity!')
app = webapp2.WSGIApplication([
('/', MainHandler)
], debug=True)
Google App Engine console:
Error: Not Found
The requested URL / was not found on this server.
Any assistance on how to correct this issue would be appreciated.

The error is indicating that the url entry in your app.yaml is not valid. Try this
url: /udacityassignment2
And as Tim pointed, the mapping should be
app = webapp2.WSGIApplication([
('/udacityassignment2', MainHandler)
], debug=True)

You can make the URL entry as below to give you more flexibility when creating your url routing table
- url: .*
script: main.app
