Attempt to index nil with 'Died'?

I made a GUI that pops up from outside the screen when a player dies but it shows this error when I die and doesn't work. Attempt to index nil with 'Died' I tried to change it to a server script but it showed the same error again so I put it back in a LocalScript.

Erroring line

Line 6

local frame = script.Parent.Frame
local player = game.Players.LocalPlayer
local character = player.Character
local humanoid = character:FindFirstChild("Humanoid")

humanoid.Died:Connect(function()
	frame:TweenPosition(
		UDim.new(0.256, 0,0.075, 0),
		"Out",
		"Quad",
		0.5,
		false
	)
	wait(3.5)
	frame:TweenPosition(
		UDim.new(0.256, 0,-1.075, 0),
		"Out",
		"Quad",
		0.5,
		false
	)
end)

LocalScript is stored inside of the ScreenGUI
