[google-appengine] Re: The server encountered an error and could not complete your request.
That typically means your app returned a 500 error code to whatever was fetching the document (it's not clear below whether you're running in a browser or making an API call from an app or something else). You should check the admin console for the deployed app and go to the logs section. Any query that returns a 500 should be tagged as an error, so if you filter on that you should see the full log for the failed query. A 500 is returned in numerous circumstances; one of the more common cases is a null pointer exception in your Java code, just to give you an idea. But the log should tell you what happened in any case. https://developers.google.com/appengine/docs/adminconsole/index - Kris On Monday, February 11, 2013 8:02:01 PM UTC-8, inviteef...@gmail.com wrote: > > Hi all, > > I used JDO to implement a query.

[google-appengine] Re: The server encountered an error and could not complete your request.
Hi Waleed, You are not seeing any errors/warnings in the logs? There are a few possibilities here. If the request hits your app: * You could be hitting the 30 seconds limit (maybe because the input is too large or something). You should see an error in the logs. * Your code could also be raising an exception that you do not catch. You should see an error in the logs. * It is also possible that the return status of the request is set to 500 somehow. In this case, if your application could silently catch the exception without logging anything. But you should be able to debug it by logging info messages in your request handler. If your request does not hit your app: * You could be hitting the simultaneous requests limit. That's a warning in the logs, but it shouldn't be reproducible every time.

Re: [google-appengine] Re: The server encountered an error and could not complete your request.
Hi Mark,
I'm testing this on my dev app, which has no load at all, so it's not
the simultaneous requests limit. Although the same problem happens on the
production app for that specific request. It's a reproducible problem. This
is what I see in the logs:

HTTP/1.1" 500 0 - "NetworkedBlogs,gzip(gfe),gzip(gfe)"
I have a logging.info() statement right at the start of the app as
follows:
def main():
logging.info("processing request")
wsgiref.handlers.CGIHandler().run(application)
But I don't see that info message in the log, so I'm taking that to mean
that the execution is not hitting my app. I don't see any other details in
the log other than what I lited above. The size of the POST body I'm sending
is 139836 bytes, which is not that big.
Any other ideas?
Regards,
Waleed

Re: [google-appengine] Re: The server encountered an error and could not complete your request.
I might have more information after a lot of testing. It seems that if an
internal error happens while processing the request on the App Engine, then
that process is killed and none of the log messages are recorded. Can
someone from Google confirm this?
That might explain why I don't see any of the my logging.info() messages,
which led me to think that that request is not hitting my app. Anyone else
experienced this?

Re: [google-appengine] Re: The server encountered an error and could not complete your request.
I think I know what's happening now, so I'm sharing it for everyone's
benefit. I was using the feedparser library to parse a feed, and that got
into some sort of infinite loop. What worries me, though, is the fact that
the App Engine didn't log any information from any of the logging.info()
messages that executed before reaching the infinite loop, which made it
really hard to find out what was going on. On localhost, the logging happens
even if the process dies eventually, but on the live app engine that doesn't
seem to be the case.
