Is there any reason as to why the value of the key DisplayName won't set based on this script?
handlers.SetDefaultPlayerVariables = function (args, context){
var displayNameUpdate = server.PlayerProfile({ PlayFabId: currentPlayerId }).PlayerProfile.DisplayName;
server.UpdateUserReadOnlyData({
PlayFabId: currentPlayerId,
Data: {
"CurrentLevel": "1",
"Losses": "0",
"MaxEnergy": "100",
"Rank": "1",
"HealSelf": "5",
"Punch": "5",
"Blind": "1",
"Explode": "1",
"Wins": "0",
"WalkSpeed": "1500",
"DisplayName": displayNameUpdate
}
})
};
