question

I'm trying to invoke the API call named UpdateUserInventoryItemCustomData, but I get back an "Invalid input parameters" error.

There is something about the Data field it doesn't like, so I'm guessing the expected format is different than what I'm passing in?

This is what's being passed in (from the log output):

	"api": 
	"/Server/UpdateUserInventoryItemCustomData",
	"request": 
	{
		"PlayFabId": 
		"EF1C1971032AF41A",
		"ItemInstanceId": 
		"C37D187D910996D1",
		"Data": 
		{
			"slot": 
			"Inventory00",
			"uses": 
			"uses"
		}
	},

And here's the error:

	"result": 
	null,
	"apiError": 
	{
		"code": 
		400,
		"status": 
		"BadRequest",
		"error": 
		"InvalidParams",
		"errorCode": 
		1000,
		"errorMessage": 
		"Invalid input parameters",
		"errorHash": 
		null,
		"errorDetails": 
		null
	}
