i am trying to make a queue system but it gives me an "unable to cast value to Object"?

Here is my code:

local requiredPlayers = 3
local playerQueue = {
	1,
	2
}
local ts = game:GetService("TeleportService")
local numOfPlayers = 1

local function hasPlayer(tab, ply)
	for i, v in pairs(tab) do
		if v == ply then
			return true
		end
	end
	return false
end

local function joinQueue(player)
	if not hasPlayer(playerQueue, player) then
		if numOfPlayers == 0 then
			numOfPlayers = 1
		else
			if numOfPlayers == 1 then
				numOfPlayers = 3
				print("player has joined the queue")
				playerQueue[numOfPlayers] = player
			end
		end
	end
end

local function queueLoop()
	print(1)
	while wait(1) do
		print(2)
		if numOfPlayers == requiredPlayers then
			print("prepare to teleport")
			local code = ts:ReserveServer(11299666436)
			print(3)
			ts:TeleportToPrivateServer(11299666436, code, playerQueue)
			print(4)
			playerQueue = {}
			print(5)
		end
	end
end

spawn(queueLoop)
script.Parent.Touched:Connect(joinQueue)

if any help could be provided it would save me

Can we get a line of error? I will edit my reply when provided.

EDIT:

It's because you're trying to Cast number values, to objects. TeleportToPrivateServer (third arg) requires a list of player OBJECTS, not UserID's. In the script you put 1, and 2 which aren't player objects and are number values.

I would also recommend table.insert(playerQueue,player) instead of using **playerQueue[numOfPlayers] = player ** as this is incredibly insufficient and can cause bugs.

(Sorry for late reply. Been busy.)

Here is an updated code just to help with your troubles. This is also correct. I would also discontinue the use of local functions unless you are creating a function, within a function. It just makes it a bit harder to use it in a proper manner.

local requiredPlayers = 3
local playerQueue = {}
local ts = game:GetService("TeleportService")

function hasPlayer(tab, ply)
	if table.find(tab,ply) then
		return true
	end
	return false
end

function joinQueue(player)
	if not player or not player:IsA("Player") then print("No Player Object. Discontinuing request.") end
	if not hasPlayer(playerQueue, player) then
		table.insert(playerQueue,player)
		queueUpdate()
		print(player.Name.." added to queue.")
	else
		print("Player is already in queue. Discontinuing request.")
	end
end

function leaveQueue(player)
	if not player or not player:IsA("Player") then print("No Player Object. Discontinuing request.") end
	if hasPlayer(playerQueue,player) then
		table.remove(playerQueue,table.find(playerQueue,player))
		queueUpdate()
		print(player.Name.." removed from queue.")
	else
		print("Player does not exist in queue. Discontinuing request.")
	end
end

function queueUpdate()
	if #playerQueue >= requiredPlayers then
		for i=1,10 do --Were going to do this for if anyone decides to join in the queue on accident.
			print(i.." until start.")
			if #playerQueue < requiredPlayers then
				print("Not enough players. Discontinuing request.")
				break
			end
		end
		print("Preparing to teleport from queue.")
		local code = ts:ReserveServer(11299666436)
		ts:TeleportToPrivateServer(11299666436, code, playerQueue)
		playerQueue = {}
	end
end

script.Parent.Touched:Connect(joinQueue)
