question

Hi, is there something wrong with the following request?

server.GrantItemsToUsers({
            ItemGrants: [{
                PlayFabId: currentPlayerId,
                ItemId: lootBoxEarnedItemId,
                Data: referenceItem.CustomData
            }]
        });

It produces the following error on playfab:

{
                "Level": "Error",
                "Message": "PlayFab API request error",
                "Data": {
                    "api": "/Server/GrantItemsToUsers",
                    "request": {
                        "ItemGrants": [
                            {
                                "PlayFabId": "XXXXX",
                                "ItemId": "lootbox.6",
                                "Data": "{\"droptable\":\"Loot Box 6\",\"type\":\"6\"}"
                            }
                        ]
                    },
                    "result": null,
                    "apiError": {
                        "code": 400,
                        "status": "BadRequest",
                        "error": "InvalidParams",
                        "errorCode": 1000,
                        "errorMessage": "Invalid input parameters",
                        "errorHash": null,
                        "errorDetails": {
                            "PlayFabId": [
                                "The PlayFabId field is required."
                            ],
                            "ItemId": [
                                "The ItemId field is required."
                            ]
                        }
                    }
                }
            }

If I modify the request to include the keys it says it's missing, I get more errors:

                "Level": "Error",

                        "PlayFabId": "XXXXX",
                        "ItemId": "lootbox.6",
                        "Data": "{\"droptable\":\"Loot Box 6\",\"type\":\"6\"}",
                        "ItemGrants": [
                            {

                                "Data": "{\"droptable\":\"Loot Box 6\",\"type\":\"6\"}"
                            }
                        ]
                    },
                    "result": null,
                    "apiError": {
                        "code": 400,
                        "status": "BadRequest",
                        "error": "InvalidParams",

                        "errorHash": null,
                        "errorDetails": {
                            "ItemGrants[0].Data": [
                                ""
                            ]
                        }
                    }
                }
            }
