Whenever I test-play my Hide and Seek game, I always see this error message appear: "invalid argument #2 to 'random' (interval is empty)". How do I solve this issue?

Full Code:

-- Services
local replicatedStorage = game:GetService("ReplicatedStorage")
local serverStorage = game:GetService("ServerStorage")

local status = replicatedStorage:WaitForChild("Values").Status

-- Config
local playersToStart = 1

-- Functions

local function chooseSeeker(availablePlayers)
	return availablePlayers[math.random(1, #availablePlayers)]
end

local function teleportPlayers(availablePlayers, spawns) -- availablePlayers: Table / spawns: Table
	for _, plr in pairs(availablePlayers) do
		if plr.Character then
			if plr.Character:FindFirstChild("HumanoidRootPart") then
				plr.Character.HumanoidRootPart.CFrame = spawns[math.random(1, #spawns)].CFrame + Vector3.new(0,5,6) <-- line with error message
			end
		end
	end
end

while wait(1) do
	
	repeat
		
		print("Not enough players in-game!")
		status.Value = playersToStart.." players or more are needed to start. (/"..playersToStart..")"
		
		wait(1)
		
	until #game.Players:GetPlayers() >= playersToStart
	
	for i = 5,0,-1 do
		status.Value = "Next round starts in "..i.." seconds."
		wait(0.1)
	end
	
	local contestants = game.Players:GetPlayers()
	
	local seeker = chooseSeeker(contestants)
	
	status.Value = "The chosen seeker is... "
	wait(2)
	status.Value = seeker.Name.."!"
	
	wait(3)
	
	local map = workspace.Map
	
	teleportPlayers(contestants, map.Spawns:GetChildren())
	wait(5)
end

According to internet research, you would get an "interval is empty" error if the second argument is less than the first argument. Your spawns table may be empty at times, causing this error; check if this is the case.
