Crawl Animation not working

This code isn’t loading my animation to my character when I join the game and my character is loaded!

game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		local Humanoid = char:WaitForChild("Humanoid")
		local Animation = Humanoid.Animator:LoadAnimation(script.Animation)
		Animation:Play()
	end)
end)

Error:

Add a Task.wait() code before LoadAnimation()
