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

I have a issue with my script. I need help!!!

for _, player in pairs(activecontestants) do
		if player then
			awardpoints(player, 1)
			if player.Character then
				local humanoid = player.Character:FindFirstChild("Humanoid")
				if humanoid then
					humanoid:UnequipTools()
				end
			end

			local randomspawn = lobbyspawns[math.random(1, #lobbyspawns)]
			player.Character:MoveTo(randomspawn.Position)

			local backpack = player:FindFirstChild("Backpack")
			if backpack then
				backpack:ClearAllChildren()
			end
		end
	end

The error is on line 11. This is a part in a long script and it is going to teleport players in my game back to the lobby and get players points for surviving the game and get rid of any tools when they spawn into lobby

Hope you can help :D

local randomspawn = lobbyspawns[math.random(#lobbyspawns)]

That might solve your issue, kind of. When math.random spits out error messages about intervals, it's normally because arg #2 is smaller than arg #1, which will happen when #lobbyspawns is 0 or 1. You might want to check the length of your table with a print because this could imply some other issue in your code.
