Good day!
https://developers.google.com/appengine/docs/python/gettingstarted/helloworld
this is the hello world that I'm trying to run.
I can seeing the
Hello, world!
Status: 500
message. however it will be turned to a "HTTP Error 500" after I hit the refresh.
and... it seems that the appengine only shows me the good result once after I re-save either app.yaml or helloworld.py
This is the trace for the good result

print 'Hello, world!'
my main.py. (app is used instead of application)
import webapp2
class hello(webapp2.RequestHandler):
def get(self):
self.response.out.write('normal hello')
app = webapp2.WSGIApplication([
('/', hello),
], debug = True)
and the app.yaml
application: helloworld

api_version: 1
threadsafe: true

static_files: favicon.ico
upload: favicon\.ico
- url: /hello
script: helloworld.app
- url: /.*
script: main.app
libraries:
- name: webapp2
version: "2.5.1"
any clue what's causing this?
Regards,
You aren't creating a helloworld.app object in your helloworld.py module.
See the lines
app = webapp2.WSGIApplications([...
in your main.py file? That creates the main.app object that's referenced by the script: main.app handler in your app.yaml.
You're referencing a helloworld.app object a couple of lines above; that object doesn't exist. Python 2.7 in App Engine doesn't support the simple module model -- no WSGI handler, just a simple script -- that's used in the 2.5 "Hello World" demo.
As presveva said, use the 2.7 Getting Started guide for less confusion.

I have tried to get a group settings with group settings API using Google App Engine 1.7.5 with python 2.5 following a simple example here.
this is my app.yaml:
application: {{APP_ID}}
version: 1
runtime: python
api_version: 1
handlers:
- url: /.*
script: main.py
and my main.py is like following:
def main():
application = webapp.WSGIApplication([('/', TestHandler)])
run_wsgi_app(application)
class TestHandler(webapp.RequestHandler):
"""Handles a request for the query page."""
def get(self):
self.response.out.write(Test())
def Test():
credentials = AppAssertionCredentials(scope='https://www.googleapis.com/auth/apps.groups.settings')
http = credentials.authorize(httplib2.Http(memcache))
service = build('groupssettings', 'v1', http=http)
group = service.groups().get(groupUniqueId='{{GROUP_ID}}').execute()
logging.error(group)
if __name__=="__main__":
main()
and this is the stacktrace telling me invalid credentials!

Have anyone got this error before or have an idea of the root cause?
Have you turned on access to the groups API through the developer console for the project? This is a simple step that is often missed by people trying to get APIs going.
Also, I'd recommend using the decorator patterns for OAuth as described here to simplify the reasoning around authorization flows.
In addition, your app.yaml should specify python27 rather than just python. App Engine runs python27.
I have a Google App Engine app with jinja2, when I force 404 error I have this error:

Here is the folder structure
Another important thing is that it works without problem in local machine (SDK), but the problem appear in production
You can explore the complete code, because this is an open source code
Thanks in advance for your help
I fixed it by removing the "default_error" on app.yaml
And the error handlers now only have:
error_handlers:
- error_code: over_quota
file: templates/errors/over_quota.html
- error_code: dos_api_denial
file: templates/errors/dos_api_denial.html
- error_code: timeout
file: templates/errors/timeout.html
I improved the code for control 404 errors, adding 500 error, with:
def handle_error(request, response, exception):
c = { 'exception': str(exception) }
status_int = hasattr(exception, 'status_int') and exception.status_int or 500
template = config.error_templates[status_int]
t = jinja2.get_jinja2(app=app).render_template(template, **c)
response.write(t)
response.set_status(status_int)
app = webapp2.WSGIApplication(debug = os.environ['SERVER_SOFTWARE'].startswith('Dev'), config=config.webapp2_config)
app.error_handlers[404] = handle_error
app.error_handlers[500] = handle_error
i have made an application using python and google app engine, the app works ok so far on localhost but when i deploy it using the google app engine launcher i get the following:

i use django 1.3 and python 2.7 is that the cause of the problem ? please help
UPDATE
here is also my yaml configutration

static_dir: files/image
- url: /files/css
static_dir: files/css
- url: /files/javascript
static_dir: files/javascript
- url: /files/page
static_dir: files/page
- url: /.*
script: legacyexample.py
is the index.html template in files/page ?
edit:
remove
- url: /files/page
static_dir: files/page
this declaration from the yaml file.
you need the html template files accessible from the .py files and not as static files.

Following this guide:
