CloudScript: UnlockContainerInstance

Hello,

Im trying to do the following:

* unlock a container using cloud script for a players

* retrieve ItemIds of the items dropped in the container (container contains a drop table)

because I want to do some extra actions on the ItemIds only

my problem is the following: when I try to access GrantedItems from the response and get an item on a specified index I can't retrieve ItemId.

it throws an error and tells me to check my argument. it Also set it to null although I have ItemIds in response.

i'm accessing the ItemIds like this: unlockContainerBox.GrantedItems[0]["ItemId"];

I have the following Code:

handlers.unlockContainer = function (args, context) 
{
  var containerID = args.containerID;
  //unlock box
  var unlockContainerBox = server.UnlockContainerInstance
  (
   		{
  			PlayFabId: currentPlayerId,
  			ContainerItemInstanceId: containerID
		}
  );
  var Item =  unlockContainerBox.GrantedItems[0]["ItemId"];
	return Item;


}

Have you tried logging the full response from UnlockContainerInstance to determine exactly what's being returned? What do you see there?

check this out.

even this doesn't work. it seems its reading it as null

but if I try with RemainingUses or UnitPrice it works fine

 var testItems = {
        "ItemId": "shield_level_5",
        "ItemInstanceId": "Unique Item ID",
        "ItemClass": "shields",
        "PurchaseDate": "2014-03-07T00:00:00Z",
        "Expiration": "2015-10-01T00:00:00Z",
        "RemainingUses": 10,
        "Annotation": "No Annotation",
        "CatalogVersion": "5",
        "BundleParent": "crate block 1",
        "UnitPrice": 0
      }
  return JSON.parse(JSON.stringify(testItems["ItemId"]));

Here is the full response of the original code using: log.info(unlockContainerBox);

It looks like you're running into the same issue as in this thread: https://community.playfab.com/questions/3816/list-is-returned-as-list.html. Can you try updating with the deserialization step?

I've already tried JSON.parse() multiple times. I also had to use JSON.stringify() inside the parse() because it threw an error.

myJSON = JSON.parse(JSON.stringify(unlockContainerBox));
firstItem = myJSON.GrantedItems[0];

now if I access firstItem like >

firstItem["itemId"]

or

 firstItem.ItemId

<<< i get error

if I access >

firstItem[0]

<I just get null <<<< this is so weird because I printed firstItem everything is there

=========

note: I already used Object.values(firstItem) << it returned an array of values which is good because everything is there when I print but when I access the array at any value that is in between "" I get null. other values like UnitPrice works fine

check this out:

log.debug() shows the value correctly

return gives me error

if I try to assign it to a var it also gives me an error

handlers.unlockContainer = function (args, context) 
{
  var containerID = args.containerID;


  //unlock box
  var unlockContainerBox = server.UnlockContainerInstance
  (
   		{
  			PlayFabId: currentPlayerId,
  			ContainerItemInstanceId: containerID
		}
  );
  
  log.debug(Object.values(unlockContainerBox.GrantedItems[0])[0]);

// if this line exist log.debug won't run
  return Object.values(unlockContainerBox.GrantedItems[0])[0];


}

Hm. It's not clear why, but yes, I'm seeing the same thing. In my testing, this resulted in getting you the Item ID in the response:

handlers.unlockContainer = function (args, context) 
{
  var containerID = args.containerID;
  //unlock box
  var unlockContainerBox = server.UnlockContainerInstance
  (
    {
      PlayFabId: currentPlayerId,
      ContainerItemInstanceId: containerID
    }
  );
  var Item = unlockContainerBox.GrantedItems[0];
  var ItemId = JSON.stringify(Item.ItemId);
  return ItemId;
}

Thats interesting. I guess its related to limitations on return in cloudscript

malsowayegh answered Oct 1, '18

it seems that I can't return the value for some reason

but I assigned it in a variable successfully and used it for other purpose.

Object.values()

// small sample of what I used


var itemID = Object.values(unlockContainerBox.GrantedItems[0])[0]
