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.
