invalid argument #2 to 'random' (interval is empty)?

The Code is:

while true do
	
	local players = game.Players:GetChildren()
	

	
	local giant = players[math.random(1, #players)]
	
	wait()
	
	for i = 1,20 do
		
		local player = game.Players:GetChildren()
		status.Value = "Intermision "..20-i
		wait(1)
	end

	for i = 1,#players do
		if players[i].Character ~= nil then
			local spawnLocation = math.random(1,#workspace.Teleports:GetChildren())
			local giantspawnLocation = math.random(1,#workspace.GiantTeleport:GetChildren())
			players[i].Character:MoveTo(workspace.Teleports:GetChildren()[spawnLocation].Position)
			giant.Character:MoveTo(workspace.GiantTeleport:GetChildren()[giantspawnLocation].Position)
			PlayerSize(giant)

		end
	end
	for s = 1,20 do
		status.Value = "Game "..20-s
		wait(1)
		for l = 1,#players do
			
			giant.Character.HumanoidRootPart.Touched:Connect(function(player)
				local humanoid = players[l].Character.Humanoid
				if humanoid.Parent.Name ~= giant.Name then
					humanoid:TakeDamage(100)
				end
			end)
		end
	end

	print(giant)

	wait(1)
	for p = 1,#players do
		

		giant.Character.Humanoid:TakeDamage(1000)
		players[p].Character.Humanoid.Health = 0
	end

end
