Why am I receiving "Unable to cast to Dictionary" error when attempting to tween a parts position?

I am trying to create a door that, when activated with a Proximity Prompt, will tween the part's position to try to the door visually swing open.

I believe I am typing the code right, yet whenever I hit Play and activate the Proximity Prompt, I get the error message: "Unable to cast to Dictionary"

Any idea what I could be doing wrong? Here is the code:

local TweenService = game:GetService("TweenService")
local door = workspace.Door

script.Parent.Triggered:Connect(function()
	print("Open")
	local tweenInfo = TweenInfo.new(
		2,
		Enum.EasingStyle.Linear,
		Enum.EasingDirection.In
	)
	local goalPos = Vector3.new(-11.45, 3, -2.2)
	local tween = TweenService:Create(door, tweenInfo, goalPos)
end)

change the goalPos variable to a table containing the position

otherwise, right above the tween:

goalPos = { goalPos }
