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

Script

for i,v in pairs(game.Workspace.Teleports:GetChildren()) do
	local dss = game:GetService("DataStoreService")
	local sv = dss:GetDataStore("Save1")
	
		game.Players.PlayerAdded:Connect(function(plr)
			local SetSuccess, errormessage = pcall(function()
			local PortalData = sv:SetAsync(plr.UserId,v)
		end)
		if not SetSuccess then
			warn(errormessage)
			
			local GetSuccess, amount = pcall(function()
				return sv:GetAsync(plr.UserId)
			end)
			if GetSuccess then
				print(amount)
			end
		end
	end)
end
