I got Error 500 on Google App Engine out nothing.
http://oladic.appspot.com/ - this got error.
The same co开发者_高级运维de runs flawlessly at: http://blogthere.appspot.com/ and http://912.latest.oladic.appspot.com/
How could this be?
This issue has been resolved. The post on the downtime-notify list is here:
http://groups.google.com/group/google-appengine-downtime-notify/browse_thread/thread/7fb8a39149de3b55
The update on the system status page is here:
http://code.google.com/status/appengine/detail/datastore/2010/02/02#ae-trust-detail-datastore-get-latency
You can see the System Status and check if the error was when the system had problems
I had this problem for 2 days, turns out it because I'm not listed on Google's "Trusted Developers List?" My only issue now is why Google doesn't return a meaningful error message..
Here's their own thread on the matter. See for yourself. http://code.google.com/appengine/forum/go-forum.html?place=topic/google-appengine-go/zdMysT6yO30
App Engine appears to be borked this morning, lots of people are having this problem on the mailing list as well.
My site has just, somewhat unexpectedly, come back online, with no work done by myself.
I assume it was a temporary problem with the App Engine, and, with any luck, your site should come back up soon.
In my case, the problem appeared when I decided to deploy the application. After inquire for a while, I figured out that the problem was being caused due the imports of simplejson (in MacOS) or json (in Windows).
The solution to this, is to import the libraries from django. In my case I did:
from django.utils import simplejson
I hope this solution will work for you.
I had a similar problem, and like Harph above i eventually realized that the use of a JSON module via the following import:
import json
was the cause of the error (at the Engine side) -something that was not problematic at the development server
I corrected this to
from django.utils import simplejson
And this has solved the problem.
thanks Harph for the tip.
Note: Another very important thing that I'd overlooked, that might actually make it harder for other devs working with the GAE for the first time, is not using the Error Logs in the Admin Console (at the datastore admin interface). This is i believe the surest way to quickly pin down the cause of problems at the GAE side (especially ones you don't see at the development server).
