Infinite yield possible on 'Workspace.YellowJeep:WaitForChild("VehicleSeat")' error?

This script should teleport a player to a position when E is inputed, i get the error in the title instead and it doesnt work, tough the error in the title is a warning and is in yellow

Code:

workspace.ChildAdded:Connect(function(Child)
	if Child.Name == "YellowJeep" then
		print("AddedJeep")
local TouchButton = false
local UIS = game:GetService('UserInputService')
local plr = game.Players.LocalPlayer
local Character = plr.Character
if not Character or not Character.Parent then
    Character = plr.CharacterAdded:wait()
end
local Root = Character:WaitForChild('HumanoidRootPart')
wait(0.5)
local Part = workspace.YellowJeep:WaitForChild("VehicleSeat")
local Position1 = Part.Position

UIS.InputBegan:connect(function(input)
    if input.KeyCode == Enum.KeyCode.E then
	print("M")
	TouchButton = false
        local mag = (Part.Position - Root.Position).magnitude
        if mag <= 20 then
            Character:MoveTo(Position1)
        else
	print("PO")
        end
end
end)

while wait(1) do
	Position1 = Part.Position
end
end
end)

btw this is a LocalScript inside StarterPlayerScripts
