I am trying to rotate a part but I keep ending up with errors

Script

local TS = game:GetService("TweenService")


local TSInfo = TweenInfo.new(
	4,
	Enum.EasingStyle.Linear,
	Enum.EasingDirection.InOut,
	5,
	true,
	1
)
local TSS = TS:Create(script.Parent, TSInfo,{CFrame = script.Parent * CFrame.Angles(0 , 0, math.rad(90))})
wait(5)
TSS:Play()

Error

Workspace.Part.Script:13: invalid argument #1 (CFrame expected, got Instance)
#2

Would

{CFrame = script.Parent.CFrame

work?
Actually yes it will i tried it
