TeleportToPrivateServer is not working?

Hello everyone, I've made a script that would teleport players to another game that is apart of the starter place but it ain't working. Any help?

Code:

local TeleportService = game:GetService("TeleportService")
 local TS = game:GetService("TeleportService")
 local Players = game:GetService("Players")
 local code = TS:ReserveServer(5488852205) 

 function onPartTouch(otherPart)
	local player = game.Players:GetPlayerFromCharacter(otherPart.Parent)
	if player then
		TS:TeleportToPrivateServer(5488852205,code,player)
end
end
script.Parent.Touched:Connect(onPartTouch)

The error that is shown on /console:

07:02:27 -- Unable to cast value to Objects Stack Begin Script 'Workspace.TeleporttoCabin.5.hello.script', Line 11 - function onPartTouch Stack End

Any support would be appreciated, thanks!
