Why is teleporting using :MoveTo() Unstable?

Hey Guys! So i wrote this and it runs perfectly, then suddenly on occasion it will run once and break giving saving it cant perform a moveto on nil..? Then on other occasions it will give that without even running once first. I make no altercations when it does this. its simply for whatever reason non-reliable. Can someone tell me why? or give me an alternative? I had used CFrame before but it was also shaky so I started using MoveTo.

ting = 0

function ontouch(Hit)
    if ting == 0 then
        ting = 1
        local char = game.Workspace:FindFirstChild(Hit.Parent.Name)
        char:MoveTo(game.Workspace.PortalHub.Spawn.Position)
        wait(0.5)
        ting = 0
    end
end

script.Parent.Touched:Connect(ontouch)
