Hi,

I am trying to debug a cloud code script.

I have some javascript object i am manipulating and i am trying to print their contents with 

Spark.getLog().debug("my obj: " + myObj);

if i print myObj as-is, i get "My Obj = [object Object]"

but if i try to JSON.stringify it, i get this exception

{"stackTrace":"\tat event/***.js:64\n","error":"Java class \"[Ljava.lang.String;\" has no public instance field or method named \"toJSON\". (event/***.js#64)","script":"***"}

 probably due to some native stuff i am loading inside

 (myObj contains playerId and displayName of the player loaded with Spark.getPlayer() among other stuff).

ps: if I send it to the client with Spark.SetScriptData("debug", myObj) I correctly get all the fields, including the native ones.

my obj is ~30ish fields, some of them are nested or arrays.

it actually is a representation of player, with its properties defined with

Object.defineProperties(user, properties.reduce(function(obj, k){
                    obj[k] = {
                        get:function(){return player.getPrivateData(k);},
                        set:function(value){player.setPrivateData(k, value);}
                    };
                    return obj;
                }, {}));

 for my custom data, and some default mappings like 

{
    ...
    get Coins() { return player.getBalance1();},
    get Friends() {
                        var t = Spark.getTeams().getTeamByOwnerIdAndTeamType(player.getPlayerId(),"friendsList");
                        if (t.length > 0)
                            return t[0].getMemberIds();
                        return [];
                    },
    ...
}

after some tests, i found the problem is due to native array of strings, and i managed to work around it with 

var r = [];
if (t.length > 0)
    r.push (t[0].getMemberIds());
return r;

 (native strings are working as expected)
