Client event not firing. Returning error. Any help?

This script is just a draft.

I am receiving this error Argument 1 missing or nil for line 41

local waitingforplayerstime = 20
local waitingforplayers = waitingforplayerstime -- for consistency throughout script
local intermission = 5
local matchtime = 120 -- 2 minutes

local numofplayers = 0
local maxplayers = 3 -- max number of players in game

local ss = game:WaitForChild("ServerStorage")	--Use waitforchild to prevent errors
local rs = game:WaitForChild("ReplicatedStorage")

local events = {}

local players = game:WaitForChild("Players")

players.PlayerAdded:connect(function()
	print("PlayerAddedTest Passed")
	print(numofplayers)
	numofplayers = numofplayers + 1
	print(numofplayers)
	wait(1)
	initiatematch()
end)

players.PlayerRemoving:connect(function()
	print("PlayerRemovedTest Passed")
	numofplayers = numofplayers - 1
end)

function initiatematch()
	if numofplayers > 1 then
		while waitingforplayers > 0 do
			waitingforplayers = waitingforplayers - 1
			print(waitingforplayers)
			if numofplayers < 2 then
				waitingforplayers = waitingforplayerstime -- stop the deployment of players if there is only 1 player in-game
				break
			end
		end
		if waitingforplayers <= 0 then
			game.ReplicatedStorage.TeamColor:FireClient() -- error here
		end
	end
end

The script is located in serverscriptservice The client event being fired is located in playerscripts The code for the client event is just a print statement to make sure the event has fired and been received. FE is not enabled.
