Read item custom data with cloudscript

Hello!

I'm trying to use a Cloudscript function to save my inventory and update the character read only data, but when I can't access item's custom data to add item stats to the character.

function SaveInventory(args) {
    args.CurrentPlayerData = !args.CurrentPlayerData ? {} : args.CurrentPlayerData;
    var characterData = args.CurrentPlayerData.characterData;
    var item = characterData.Head;
    //var itemID = GetItemByID(item);
    var itemCustomData = JSON.parse(item.CustomData);
    var head = itemCustomData.damage;
    characterData.Defense += head;


    // API params
    var updateDataRequest = {
        PlayFabId: currentPlayerId,
        CharacterId: args.CurrentPlayerData.CharacterId,
        Data: { CharacterData: JSON.stringify(characterData) },
        Permission: "Public"
    };
    server.UpdateCharacterReadOnlyData(updateDataRequest);
}

In characterData I have a string containing the itemID which is the same as the on in Playfab, so I guess I can skip the GetItemByID line. The script fails at the JSON.parse, any ideas on why this fails?

The CustomData of the specific inventory item instance is the JSON object that needn’t be parsed. You can access the K/V pairs of it directly. It’s our test function, you can refer to it to modify the code.

handlers.GetInventoryData = function (args, context) {
    var GetInventoryResult = server.GetUserInventory(
        {
            PlayFabId: currentPlayerId
        }
    );
    var InvertoryItemData = GetInventoryResult.Inventory[0].CustomData;
    var damage = InvertoryItemData.damage;
    // return the value of "damage" field
    return damage;
}
