Cannot store Instance in data store. Data stores can only accept valid UTF-8 characters

Help and Feedback Scripting Support

I was trying to make a data script following an alvin blox tutorial, I encountered some problems so I changed it according to some things I saw in the forums but it still doesn’t save, it has access to API services. Thanks in advance

My Terrible Script:

local DataStoreService = game:GetService("DataStoreService")
local MyDataStore = DataStoreService:GetDataStore("myDataStore")

game:WaitForChild("Players").PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player

	local JumpPower = Instance.new("IntValue")
	JumpPower.Parent = leaderstats
	JumpPower.Name = "JumpPower"
	JumpPower.Value = 0
	
	local data 
	
	local success, errormessage = pcall(function()
		data = MyDataStore:GetAsync(player.UserId.."-JumpPower")
	end)
	
	if success then 
		JumpPower.Value = data
	else
		print("There was an error whilst getting your data")
		warn(errormessage)
	end
end)

game.Players.PlayerRemoving:Connect(function(plr)
	
	local success, errormessage = pcall(function()
		MyDataStore:SetAsync(plr.UserId, plr.leaderstats.JumpPower.Value)	
	end)

	if success then
		print("Data Sucessfully Saved")
	else
		print("There was an error")
		warn(errormessage)
	end
	
	
end)

I can’t really see anything wrong with this. Try resetting the datastore by changing the name, something like myDataStore2, doesn’t really matter.

It is in the error: You can’t store instances in data stores.

You should serialize the instance, and then use JSONEncode (better methods exist but JSONEncode is the simplest).

I can’t actually see any instance assignment, but the error says you’ve done some.

Unrelated issue when you’re calling GetAsync, you’re passing player.UserId.."-JumpPower", but when you’re calling SetAsync you’re only passing player.UserId as the key.

You can not store instances in data stores normally. However, you could use a serialization module to store them. I am not going to explain what that is but you should search it up.

#6

Not sure why it says your trying to store an instance but try adding FindFirsrChild() or WaitForChild()

Also add a print before the “SetAsync” like this:

Print(plr.leaderstats.JumpPower.Value)

This is just to see if JumpPower is an instance or integer

Ah thanks for this, I just tried it and the data always returns as 0

this is a new problem that has arisen
