I keep getting a StatisticVersionInvalid response when posting a score with a version. What's the problem?

/**
 * Update the current players score 
 * @param args.statName Name of the statistic to update. 
 * @param args.score The score to post
 * @param context
 * @returns {*}
 */
handlers.updatePlayerScore = function (args, context) {
    var score = args.score;
    var stat = args.statName;
    var version = args.version;
  
    var request = {
        PlayFabId: currentPlayerId, Statistics: [{
            StatisticName: stat,
            Value: score
        }]
    };


  	if(version != null){
      request.Statistics[0].Version = version;
    }
  
    log.debug(request.Statistics);
    return server.UpdatePlayerStatistics(request);
};




Above is my server code i'm using. Unity side i'm sending along an int for the version.

Can someone explain to me why this isn't working?

That error is returned if you're trying to write to a statistic version that doesn't exist yet. You can only write to the currently active version of the statistic. The call takes a version to allow you to control whether you actually write to the statistic if it versioned during play.

For completeness, if you try to write to a previous version of the statistic, you'll get the error StatisticVersionClosedForWrites.

Ah got it thanks for the heads up. The versioning system confused me a little bit but after some reading and this post things are adding up.
