I'm having problems with TweenCamera on my menu, does anyone know what it might be?

I'm trying to make the menu in the corner of the screen (but that's not the problem) and in the meantime it is showing an image of a part of the map, however, it happens that the beginner shows and then errors start to occur, does anyone know what could it be?

Script(in screenGUI):

wait()

local Tween = game:GetService("TweenService")

local Cam = workspace.CurrentCamera
local CamPoints = workspace:WaitForChild("CameraPoints")

local function TweenCameraPos(Point,Speed)
	Tween:Create(Cam,TweenInfo.new(Speed,Enum.EasingStyle.Linear),{CFrame = Point.CFrame}): Play()
end			

Cam.CameraType = Enum.CameraType.Scriptable
Cam.FieldOfView = 50

while true do
   Cam.CFrame = CamPoints:FindFirstChild("1").CFrame
   TweenCameraPos(CamPoints:FindFirstChild("2"),3)
    wait(3)
end
