Facebook mobile OAuth redirect_uri

Acknowledging that the authenticated referral mechanism is currently not working with the mobile web settings for Facebook applications, I'm running into an issue with verifying an access token based on a returned code.

The URL I'm trying to fetch an access token for is: https://staging.fanhood.com/facebook/mobile/challenge?fh_gameChallengeID=2678&ref=web_canvas&refid=9&refsrc=http://apps.facebook.com/fanhood-dev/challenge&returned=true

This is the URL that the visitor is sent to after being pre-authenticated from this URL: http://apps.facebook.com/fanhood-dev/challenge?fh_gameChallengeID=2678. However, unlike regular authenticated referrals, there is no additional data passed into the URL so that the application can shortcut the oauth redirect loop.

At this point, I'm redirecting the visitor to the mobile OAuth dialog to authenticate them: http://m.facebook.com/dialog/oauth?client_id=250258605018414&redirect_uri=https%3A%2F%2Fstaging.fanhood.com%2Ffacebook%2Fmobile%2Fchallenge%3Ffh_gameChallengeID%3D2678%26ref%3Dweb_canvas%26refid%3D9%26refsrc%3Dhttp%3A%2F%2Fapps.facebook.com%2Ffanhood-dev%2Fchallenge%26returned%3Dtrue&scope=email%2Cfriends_about_me%2Cfriends_education_history%2Cfriends_hometown%2Cfriends_interests%2Cfriends_likes%2Cfriends_location%2Coffline_access%2Cpublish_actions%2Cpublish_stream%2Cuser_activities%2Cuser_birthday%2Cuser_education_history%2Cuser_hometown%2Cuser_games_activity%2Cuser_interests%2Cuser_likes%2Cuser_location&response_type=code&display=touch

When the user is redirected back, I do receive a code to exchange:

Code: AQBCH25OC57BiMBgj3rCKGhkFi0ypp0R8e2yKGwFfhml9x1B47-w2Baex8oZ3BKgb2NhziRnSIuJ1MV9hErKBUhu0YqxaonwFF_7mcqozwpy3Ch08rkNh-YEIa6HV_LHxl6pymfkAbQEMgSA6F4BdtINsCQ7QlLpcRwrZWkzxZVyJbJDnqOesB3zFLr5ohpgtpQ

However, none of my requests to exchange this code are working currently. I'm trying different variations of the redirect_uri format, none of which are working:

Original URL as redirect_uri:

I have a mechanism in place to strip out specific query parameters, re-order them alphabetically, and re-assemble so that redirect_uris are consistent across requests. In this case, the redirect_uri matches exactly to what was passed to the dialog URL: https://staging.fanhood.com/facebook/mobile/challenge?fh_gameChallengeID=2678&ref=web_canvas&refid=9&refsrc=http://apps.facebook.com/fanhood-dev/challenge&returned=true == https://staging.fanhood.com/facebook/mobile/challenge?fh_gameChallengeID=2678&ref=web_canvas&refid=9&refsrc=http://apps.facebook.com/fanhood-dev/challenge&returned=true

https://graph.facebook.com/oauth/access_token?client_id=250258605018414&client_secret=xxx&redirect_uri=https%3A%2F%2Fstaging.fanhood.com%2Ffacebook%2Fmobile%2Fchallenge%3Ffh_gameChallengeID%3D2678%26ref%3Dweb_canvas%26refid%3D9%26refsrc%3Dhttp%3A%2F%2Fapps.facebook.com%2Ffanhood-dev%2Fchallenge%26returned%3Dtrue&code=AQBCH25OC57BiMBgj3rCKGhkFi0ypp0R8e2yKGwFfhml9x1B47-w2Baex8oZ3BKgb2NhziRnSIuJ1MV9hErKBUhu0YqxaonwFF_7mcqozwpy3Ch08rkNh-YEIa6HV_LHxl6pymfkAbQEMgSA6F4BdtINsCQ7QlLpcRwrZWkzxZVyJbJDnqOesB3zFLr5ohpgtpQ&access_token=250258605018414%7C65adc2f073d3c901d02a7329c6acba21

Blank redirect_uri attempt for authenticated referrals:

https://graph.facebook.com/oauth/access_token?client_id=250258605018414&client_secret=xxx&redirect_uri=&code=AQBCH25OC57BiMBgj3rCKGhkFi0ypp0R8e2yKGwFfhml9x1B47-w2Baex8oZ3BKgb2NhziRnSIuJ1MV9hErKBUhu0YqxaonwFF_7mcqozwpy3Ch08rkNh-YEIa6HV_LHxl6pymfkAbQEMgSA6F4BdtINsCQ7QlLpcRwrZWkzxZVyJbJDnqOesB3zFLr5ohpgtpQ&access_token=250258605018414%7C65adc2f073d3c901d02a7329c6acba21

redirect_uri structured as our mobile canvas URL:

Does anyone know which redirect_uri format Facebook uses for mobile OAuth requests? And if query parameters are supported? This same URL works for our regular canvas application, just not our mobile version.

See Authenticated Referrals & Server-Side Auth Flow - What is the redirect_uri?

When I stripped the request_uri portion after &code=... it started working.
