My simple application which just fetches the contents from a given URL is working fine on local server, but on deployment gives error. Check here
The application consists of just two files which I am including here
compare-hatke.py
from google.appengine.api import urlfetch
url = "http://www.google.com/"
result = urlfetch.fetch(url)
if result.status_code == 200:
print(result.content)
app.yaml
application: compare-hatke
version: 3
runtime: python27
api_version: 1
threadsafe: true
handlers:
- url: /.*
script: compare-hatke.app
Log - Version 1
Traceback (most recent call last):
File "/python27_runtime/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 196, in Handle

Now, I am completely clueless why this is not working. Any suggestion or help would be crucial.
Thanks !

When attempting to pull in the grpcio library along with Cloud Endpoints Framework, it causes an error when running it through dev_appserver.py. When these changes are pushed to Google Cloud Platform App Engine the error does not present itself.
I have tried changing the versions of google-endpoints, grpcio, and six, but none of the combinations resolved the error. I have run into the error on both Windows and Ubuntu.

Recreating the issue
Make sure you have Google Cloud SDK installed.
Clone the python-docs-samples repository:
https://github.com/GoogleCloudPlatform/python-docs-samples.git
Navigate into echo sample
cd python-docs-samples/appengine/standard/endpoints-frameworks-v2/echo
Start dev_appserver
dev_appserver.py app.yaml
Send a POST test to make sure it works.
curl -d '{"content":"time"}' -H "Content-Type: application/json" -X POST http://localhost:8080/_ah/api/echo/v1/echo
With the echo application working, now install grpcio with the version GCP uses.
pip install grpcio==1.0.0
Edit the app.yaml file to include the grpcio library, so your file will look like this.
runtime: python27
threadsafe: true
api_version: 1
basic_scaling:
max_instances: 2

# [END env_vars]
Start dev_appserver.py again.
dev_appserver.py app.yaml
Send the POST again.
curl -d '{"content":"time"}' -H "Content-Type: application/json" -X POST http://localhost:8080/_ah/api/echo/v1/echo
The error I placed above should show up in the output of the dev_appserver.py.
I upload the Google App Engine application which is at the url developers.google.com/appengine/docs/python/memcache/usingmemcache#Memcache

Make sure that you have the following files in the path that you are uploading your application from:
index.yaml (auto-generated; you don't need to add or change anything in here at this point).
favicon.ico (in the correct format; should be 16x16 or 32x32 pixels if I remember correctly).
main.py (mapping all the paths in your web-site; example given below):
from webapp2 import WSGIApplication
from Server import MainRequestHandler
from Server import SomeRequestHandler
from Server import OtherRequestHandler
app = WSGIApplication([
('/' ,MainRequestHandler),
('/abc' ,SomeRequestHandler),
('/def' ,SomeRequestHandler),
('/xyz' ,OtherRequestHandler),
])
app.yaml (with the following contents; using <...> where you need to set a value):
application: <the app-id you chose when use signed in for GAE>
version: 1
runtime: python27
api_version: 1
threadsafe: yes
handlers:
- url: /favicon\.ico
static_files: favicon.ico
upload: favicon\.ico
- url: .*
script: main.app
libraries:
- name: webapp2
version: "2.5.1" // you might need to change this as well
Note:
if you wish to avoid handling 'favicon.ico' request, then you must remove the reference in file 'app.yaml'.
Supplemental:
You will need to implement all the request handlers imported in 'main.py'.
In the example above, 'main.py' expects to find them in a Python module named 'Server'.
Each request handler must inherit class RequestHandler, imported from webapp2.
Supplemental #2:
In order to solve the 'PIL' issue (had a similar problem if memory serves correctly), simply install it.
From a Windows command line, enter: pip install pil.
I am following google app engine getting started tutorials. I am at this point; https://developers.google.com/appengine/docs/python/gettingstartedpython27/templates
I have tried to follow it to the point, but when I started my application from google app engine launcher, I see this in the logs;

Here is how my app.yaml file looks like;

runtime: python27
api_version: 1

libraries:
- name: webapp2

- name: jinja2
version: latest
indexes:

What am I doing wrong here?
The tutorial doesn't tell you to put indexes into app.yaml. They go in a separate file, index.yaml. But you usually don't have to bother, as the dev server will create them for you when you run your code locally.
I've been trying to use web.py to run a simple web app on Google App Engine but have been running into some pretty basic errors. I've searched over the site and haven't found anything to address my issue. Here is the outline of the code I'm trying to run:
import web
urls = (
"/","Index"
)
app = web.application(urls,globals())
render = web.template.render('pages/', base="layout")
class Index:
def GET(self):
#code...
if __name__ == "__main__":
app.cgirun()
and this is the app.yaml code:
application: #appname
version: 1
runtime: python27
api_version: 1
threadsafe: true
handlers:
- url: /.*
script: home.app
- url: /static
static_dir: static
But then I get this in the log:
2013-08-22 06:11:13 Running command: "['C:\\Python27\\pythonw.exe', 'C:\\Program Files\\Google\\google_appengine\\dev_appserver.py', '--skip_sdk_update_check=yes', '--port=8080', '--admin_port=8000', 'C:\\.....\\root\\home-gae']"

The AttributeError is confusing me because there does appear to be a call method in web/application module. Any ideas? Any thoughts would be appreciated.
I found a way to work it out.
import web
urls = (
"/.*", "hello"
)
application = web.application(urls, globals())
#app = web.application(urls, globals())
class hello:
def GET(self):
return "HelloWorld"
#app = app.gaerun()
#app.cgirun()
app = application.wsgifunc()
using "app = application.wsgifunc() ", then the code would work well.
First, there is a little problem with your app.yaml. You need to put your static handler before the catch-all handler:
handlers:
- url: /static
static_dir: static
- url: /.*
script: home.app
Otherwise, you will not be able to serve static files.
To fix your issue with the website not loading, it looks like the development server is trying to treat your CGI app as a WSGI app. Try to fit you home.py file to the official example for web.py on GAE. That is, get rid of the if __name__ == "__main__:" part and simply replace it with:
app = app.gaerun()
I am facing same issue with google app engine application. It works on SDK (localhost), not working when uploaded to appengine. Deployment was successful. I am stuck on this!!! Any help appreciated.

Your problem is that the templates your are trying to load are residing in your static directive html .
There is no need to deploy templates as static resources - in fact you probably shouldn't.
When you deploy static resources they are not normally readable by your application.
Recently an app.yaml directive was added to allow you to read these resources.
Unless there is html files you wish to statically serve, just drop the /html static directive, or move your templates somewhere else.
or add the directive. application_readable to the /html static handler
see the docs for static handlers https://developers.google.com/appengine/docs/python/config/appconfig#Static_Directory_Handlers
Personally I would recommend against being able to statically serve jinja templates as well use them for rendering.
Why does this work in the dev environment - the dev environment doesn't use different storage mechanisms for serving static and application readable resources.
You can't store your templates in a static directory.
Simply remove the /html handler from app.yaml like so:
application: cloud-chess
version: 2
runtime: python27
api_version: 1
threadsafe: yes
handlers:
- url: /favicon\.ico
static_files: favicon.ico
upload: favicon\.ico
