TeleportData not passing with my new system

Help and Feedback Scripting Support
#1

Hello! I am currently trying to pass TeleportData through a RemoteEvent, but it is not working:

Client side:

local maps = script.Parent

for i, v in pairs(maps:GetDescendants()) do
	if v:IsA("TextButton") then
		v.MouseButton1Click:Connect(function()
			local map = v.Parent.Name
			game:GetService("ReplicatedStorage"):WaitForChild("GamemodeTP"):WaitForChild("FreeDrive"):FireServer(map)
		end)
	end
end

Server Side:

local TS = game:GetService("TeleportService")
local code

game:GetService("ReplicatedStorage"):WaitForChild("GamemodeTP"):WaitForChild("FreeDrive").OnServerEvent:Connect(function(Player, map)
	code = TS:ReserveServer(6203111795)
	TS:TeleportToPrivateServer(6203111795, code, {Player}, map)
end)

Everything is teleporting, but TeleportData comes up as nil.
If you can help, please let me know. Thanks, WE

The Fourth Parameter is the Spawn name , so pass nil for the 4th parameter and skip it since its optional and in the 5th Parameter pass the map.
