How do I debug "error=Grant: missing session or misconfigured provider" about grant HOT 10 CLOSED

This generic error message was introduced here #23 Is it possible that you are experiencing it in similar circumstances?

from grant.

I start at:
get /connect/<my-provider> {} 302 which redirects me to OAuth2 server.

I then get redirected back to:
get /connect/<my-provider>/callback {"code":"<code>","state":"<state>"} 200

When looking at the grant variable (in grant npm package) it is set to {}. It looks as if the session never got set.

Missing session can definitely result in that error. Which framework+version do you use, Express, Koa, Hapi?

Take a look at these tests: https://github.com/simov/grant/blob/master/test/consumer/express/error.js#L180-L243

If the bare minimum configuration is missing in either the connect or the callback routes in Grant, then Grant simply tells you that either your configuration is incorrect, or your session data is missing for some reason.

Either way Grant is not trying to fix your errors, if you provide me with a code example sufficient enough to reproduce the bug, I would probably be able to help you.

I'm using Hapi.

I've investigated this further, and it seems that all cookies stored by yar get wiped upon return from the my OAuth2 provider. It looks like this issue is either coming from yar or my provider.

This issue can be closed for now. It seems most likely that the issue isn't being caused here.

Can you give me the exact version of Hapi and Yar that you are using? That way I can at least run the test suite against them. Currently the Hapi version used for testing is pinned to an older version due to compatibility issues with older versions of Node.

from grant.

Sure, here you go

Edit: I've also tried it with node 4.5.0 and npm 2.15.9 with the same results

from grant.

Tests seems to be passing on my end. I'm closing this issue for now, feel free to re-open it and/or add something to it.

I've had some success with Safari, but not Chrome or Firefox. It could possibly be related to the way the cookies and sessions are set. If I figure this out I'll add the solution in case anyone else has the same issue in the future.

That would be great! 👍

The issue appears to be with yar, and so I've opened a new ticket:
