No matter what I try, it won't move or pathfind!

local pathfindingService = game:GetService("PathfindingService")

local root = script.Parent.HumanoidRootPart
local zombie = script.Parent.Zombie
local spawnCF = root.CFrame

function findPlayer()
	for _, v in next, game.Players:GetPlayers() do
		if v.Character then
			local char = v.Character
			if char:FindFirstChild("Humanoid") and char:FindFirstChild("HumanoidRootPart") then
				local pRoot = char.HumanoidRootPart
				if pRoot then
					if (pRoot.Position - root.Position).magnitude <= 30 then
						return v
					end
				end
			end
		end
	end
	return nil
end

while wait() do
	local player = findPlayer()
	if player then
		local path = pathfindingService:ComputeRawPathAsync(root.Position + Vector3.new(root.Position.X, root.Position.Y, root.Position.Z + 2), player.Character.HumanoidRootPart.Position + Vector3.new(player.Character.HumanoidRootPart.Position.X,  player.Character.HumanoidRootPart.Position.Y,  player.Character.HumanoidRootPart.Position.Z + 2), 500)
		local coords = path:GetPointCoordinates()
		for _, c in next, coords do
			zombie:MoveTo(c.Position)
		end
	end
end

Can't seem to figure out the problem. No errors in output; help, please!
