Game teleport help?

So I am developing a game that starts with a GUI intro and when you press play it will teleport you to a game which I have linked as an other game in the game settings. I want this place to be a start place and be able to teleport the player to the linked game. It keeps coming up with this error:

15:11:54.485 - httpGet http://assetgame.roblox.com/Game/PlaceLauncher.ashx?request=RequestGame&placeId=344603152&isPartyLeader=false&gender=&isTeleport=true failed. Trying again. Error: HTTP 400 (HTTP/1.1 400 Bad Request). Elapsed time: 0.261374 15:11:54.719 - Teleport exception: HTTP 400 (HTTP/1.1 400 Bad Request)

the code I have so far is:

script.Parent.Options.Button.MouseButton1Click:connect(function()
    if Deb == 0 then Deb = 1
        script.Parent.Title.Text = ""
        for i = 1,50 do
            script.Parent.Title.BackgroundTransparency = script.Parent.Title.BackgroundTransparency -0.02
            script.Parent.Title.TextTransparency = script.Parent.Title.TextTransparency -0.02
            script.Parent.Title.TextStrokeTransparency = script.Parent.Title.TextStrokeTransparency -0.02
            wait(0.1)
        end
        script.Parent.CameraIntro.Disabled = true
        script.Parent.Title2.Visible = false
        script.Parent.Options.Visible = false
        local camera=game.Workspace.Camera
        script.Parent.Title.Text = "Time warp in progress, see you soon!"
        wait(1)
        game:GetService("TeleportService"):Teleport(344603152, game.Players.LocalPlayer) --344603152 is the place i'm trying to teleport to




        script.Parent.IntroM:Stop() -- music
        script.Parent:Destroy() -- destroy the intro
    end
end)

I want to keep it so that people can only join the starting place to join actual game rather than being able to just join or press play. I have also looked at The guide on the wiki but it has not been of any use. The goal is to make it like in the plaza minigames, you press a play button and it will teleport you to a go karting or infection game

Any help will be appreciated
