question

I want to add a tag to a player calling a cloud script to do this since its only exposed in the server api and this is what i did but it doesnt work so what is the correct way i saw somewhere instead of TagName it said TagValue so this might be the issue but i took TagName from here :

https://api.playfab.com/documentation/Server/method/AddPlayerTag

handlers.onRegister = function (args, context) {


  
  var tag = args.tag;


    var request = {
        PlayFabId: currentPlayerId, 
      	TagName : tag
    };


    var playerStatResult = server.UpdatePlayerStatistics(request);
};
