endMatchInTurnWithMatchData:completionHandler: Fails with invalid state

In my turn based game, I receive the following error indicating the session is in an invalid state and that the game is not active:

2014-06-26 15:46:04.684 myApp[14498:60b] Error Domain=GKErrorDomain Code=24 
"The requested operation could not be completed because the session is in an invalid state." 
UserInfo=0x16d074a0 {GKServerStatusCode=5101, NSUnderlyingError=0x16d09fb0 
"The operation couldn’t be completed. status = 5101, Game is not active, session state is Complete", 
NSLocalizedDescription=The requested operation could not be completed because the session is in an invalid state.}

This error occurs when I call endMatchInTurnWithMatchData:completionHandler: (at this point in time, its the local player's turn and he is Quitting the game). However, I do not understand what is wrong with the current state. Prior to calling this method, I printed the match object. Here is the content:

currentMatch object is: 
<GKTurnBasedMatch 0x16d5e690 - matchID:c53a9ef1-d4ce-4da3-a2f3-9220df917615 bundleID:com.myCompany.myApp 
status:GKTurnBasedMatchStatusOpen message:'' creationDate:2014-06-26 20:43:17 +0000 
currentParticipant:
<GKTurnBasedParticipant 0x16d430d0 - playerID:G:1386520835 (local player) status:Done matchOutcome:Quit lastTurnDate:2014-06-26 20:43:35 +0000 timeoutDate:(null)> 
participants:
<GKTurnBasedParticipant 0x16d430d0 - playerID:G:1386520835 (local player) status:Done matchOutcome:Quit lastTurnDate:2014-06-26 20:43:35 +0000 timeoutDate:(null)>,
<GKTurnBasedParticipant 0x16d526c0 - playerID:G:109161898 status:Active matchOutcome:Won lastTurnDate:2014-06-26 20:43:54 +0000 timeoutDate:(null)> matchData.length:712 matchDataMaximumSize:65536 exchanges:(null)>

As you can see, the status of the match is GKTurnBasedMatchStatusOpen. If I'm not mistaken, that tells me that the game IS active. Also, each participant has a matchOutcome that is not "None" which is a requirement before sending endMatchInTurnWithMatchData:completionHandler:.

Here is my sequence of code to end the match when this local player quits:

[currentMatch participantQuitInTurnWithOutcome:GKTurnBasedMatchOutcomeQuit nextParticipants:currentMatch.participants turnTimeout:1.0 matchData:data completionHandler:nil];

NSLog(@"currentMatch object is: %@", currentMatch);

[currentMatch endMatchInTurnWithMatchData: data
                        completionHandler: ^(NSError *error) {
                           if (error) {
                               NSLog(@"%@", error);
                           }
                           else {
                               NSLog(@"match ended successfully");
                           }
 }];

Please tell me what is wrong with my approach to end the match or with the state of the session/match that is causing this error or suggest to me what else I should verify to determine the source of the problem.

I'm pretty late to the party here, but the problem is calling ParticipantQuitInTurnWithOutcome first. Once you do that, you're no longer the owner of the turn. And then when you try to endMatchInTurnWIthMatchData (key being the clause "inTurn") you're no longer the owner, so you're not in a valid state to do so.
