Sword Animation works in studio but does not work in game and getting error?

I want a sword animation to play and it works in studio but not in game and I have tried turning on filtering but that did not work. I also get an error saying that the sword animation could not be loaded when I play the actual game.

local CanAttack = true

script.Parent.Activated:connect(function()
	local attack = script.Parent.Parent.Humanoid:LoadAnimation(script.Attack)

	if CanAttack == true then
		attack:Play()
		CanAttack = false
		wait(1)
		attack:Stop()
		CanAttack = true
		script.Parent.CanDamage.Value = true

	end
end)
