Why won't my clone walk to the position?

i'm making a script in which if you press the key "C" then it makes a clone of your character and the clone attacks near by npcs but my script isn't working. I tried to use pcall function but it still doesn't work. Any help?

Here is my script.

game.ReplicatedStorage.Events.CloneEvent.OnServerEvent:Connect(function(plr)
	plr.Character.Archivable = true
	wait()
	local clone = plr.Character:Clone()
	clone.Parent = workspace
	clone.Humanoid.DisplayDistanceType = Enum.HumanoidDisplayDistanceType.None
	clone.HumanoidRootPart.CFrame = plr.Character.UpperTorso.CFrame + Vector3.new(0,0,5)
	local player = game.Players:GetPlayerFromCharacter(plr.Character)
	local NPC = workspace:FindFirstChildWhichIsA("Model")
	if NPC and NPC ~= player then
	local animation = Instance.new("Animation",clone)
	animation.AnimationId = "http://www.roblox.com/asset/?id=742640026"
	local play = clone.Humanoid:LoadAnimation(animation)
	play:Play()
	pcall(function()
		local path = game:GetService("PathfindingService"):CreatePath()
		local goal = NPC.HumanoidRootPart.Position
		path:ComputeAsync(clone.HumanoidRootPart.Position,goal)
		local points = path:GetWaypoints()
		if path.Status == Enum.PathStatus.Success then
			for _, point in pairs(points) do
				if point.Action == Enum.PathWaypointAction.Jump then
					clone.Humanoid.Jump = true
						while true do
						wait()
						clone.Humanoid:MoveTo(point.Position)
						end
					end
				end
			end
		end)
	end
end)
