Getting 500 Error processing OAuth 2 request sometimes before requesting access token.

[Aditya Hajare]

I'm getting following error sometimes after user have clicked allow
access button.. i.e. before requesting access token.
Error Response from google server :
HTTP/1.0 500 Error processing OAuth 2 request Cache-Control: no-cache,
no-store, max-age=0, must-revalidate Pragma: no-cache Expires: Fri, 01

I have tried with many different gmail accounts and same error is
returned sometimes. It does not occur regularly.
Kindly Help. Cheers!

Hi,

Are you seeing this error when swapping the authorization code? Not
sure what flow you are using.

Thanks,
Marius

Yes that is when i'm seeing it.
I've followed this documentation : http://code.google.com/apis/accounts/docs/OAuth2.html
Thanks and Cheers!

Hello,

We appreciate your help debugging this. Is it possible for you to send
the url that is in the address bar when you are on the approval page?
I know by the time you get the 500 it's probably too late to get the
url, but if all your requests are the same, it will help narrow it
down a little.

Hello David,
This is the url in approval page addressbar when 500 is encountered :
https://accounts.google.com/o/oauth2/auth?scope=https://www.google.com/m8/feeds/&client_id=772581682774.apps.googleusercontent.com&hl=en-GB&from_login=1&pli=1&response_type=code&redirect_uri=http%3A%2F%2Fwww.adiinviter.com%2Fforums%2Fadmincp%2Fvb415%2Fadi_handle.php%3Fprovider%3Dgmail

This is the url in approval page addressbar when everything is working
fine :
https://accounts.google.com/o/oauth2/auth?scope=https://www.google.com/m8/feeds/&client_id=772581682774.apps.googleusercontent.com&hl=en-GB&from_login=1&pli=1&response_type=code&redirect_uri=http%3A%2F%2Fwww.adiinviter.com%2Fforums%2Fadmincp%2Fvb415%2Fadi_handle.php%3Fprovider%3Dgmail

Thanks for you time in this matter. I strongly appreciate your help.
Kindly help.. Cheers!

Hi again,

I've tried those URLs a few times and I can't seem to reproduce your
issue. Are you doing anything odd like doing lots of these same
requests very quickly? Or maybe doing lots of grants with no revokes?
If you see the issue again, please respond quickly and we might be
able to catch it in our logs.

I am facing the same issue.
And someone else in this thread: https://groups.google.com/forum/#!topic/oauth2-dev/NOg-bzxhT1I


I can get the access token if I redo the request to https://accounts.google.com/o/oauth2/token

[Aditya Hajare]

Hello David,
There are same requests with approx 2 - 5 mins intervals.
Another thing is i'm granting permission without revoking old grants.
But the problem is, this happens even at the first time grants on
different gmail accounts.
Rite now i'm resending request to https://accounts.google.com/o/oauth2/token
if i get above error. These requests are sent after 1000ms delay (5
tries). Now it seems the problem has reduced to 20% - 30% but sure it
does occur 70% times.
You may check our logs because there has been many such errors i have
generated rite now. Thanks for all your help.
Cheers!

Hello David,
After going through numerous codes and oAuth mechanisms several times,
i would like to ask you, does my website, google's server and user
being geographically in different places causing this error?
I think there might be some user data redundancy is caused in these
moments which is causing google's server to reject token. If above
cause is true then as far as i can guess, this is actually caused by
delay between requests due to geographical dispersion. Currently i
cannot think of any quick patch on this rather than just adding some
delay between repetitive requests to obtain access token. Still this
will fail 70% times.
You asked for my ip on 21st Sep. Did you get anything from it?
Thanks alot for all your time and concern. I strongly appreciate it.
Cheers!

P.S. If the problem i mentioned above is true then does google already
working on it? how long can we expect to get this issue fixed? Cheers!
