Tween isn't working and there is nothing in output. What's the error?

So. I was trying to make this thing when you press the key, E on your keyboard. The door tweens. But it doesn't show anything in the output. Here is the code, this code is written in a regular script, not a local script, not a module script.

    local UIS = game:GetService("UserInputService")
    local MaxDistance = 5
    UIS.InputBegan:Connect(function(input, player)
        if input.KeyCode == Enum.KeyCode.E then
        local HumanoidRootPart = player.Character.HumanoidRootPart
        local MainPart = game.Workspace.MainPart
        local TweenService = game:GetService("TweenService")
        if HumanoidRootPart.Position - MainPart.Position.Magnitude <= MaxDistance then
            local TweenInformation = TweenInfo.new(
                3,
                Enum.EasingStyle.Sine,
                Enum.EasingDirection.Out,
                0,
                true,
                1
            )
            local Properties = {
                Size = Vector3.new(6.27, 0.05, 2);
            }
            local Tween = TweenService:Create(MainPart,TweenInformation,Properties)
            Tween:Play()
        end
        end
    end)
