Cannot resume dead coroutine [SOLVED]

[DERKINGIMRING112 (Liam)]

“cannot resume dead coroutine” is the error I got in this code

local RS = game:GetService("ReplicatedStorage")
local CameraShaker = require(RS.Modules:WaitForChild("CameraShaker"))
local debounce = false
local Anim = Instance.new("Animation")
Anim.AnimationId = "rbxassetid://13470967554"
local track1 = game:GetService("Players").LocalPlayer.Character:WaitForChild("Humanoid"):LoadAnimation(Anim)

--Settings--
local Cooldown = 8
local Cooldown2 = 8  --just for the countdown (has to be the same as the first Cooldown)
local ToolBarHideTime = 3
--Settings--

local countdown = coroutine.wrap(function()
	for i=Cooldown2, 0, -1 do
		script.Parent.Name = "Cooldown: ".. i
		task.wait(1)

		if i == 0 then
			script.Parent.Name = "Barrage"
			Cooldown2 = Cooldown
			debounce = false
		end
	end
end)

script.Parent.Equipped:Connect(function()
	if debounce == false then
		debounce = true
		RS.Events.Barrage:FireServer()		
		track1:Play()


		countdown() -- here is the error


		task.wait(Cooldown)
		--debounce = false
	end	
end)

RS.Events.Barrage.OnClientEvent:Connect(function()
	
	game:GetService("Lighting").BlurEffect.Size = 5
	
	game:GetService("TweenService"):Create(game:GetService("Lighting").BlurEffect, TweenInfo.new(1, Enum.EasingStyle.Exponential, Enum.EasingDirection.InOut, 0, false, 0), {Size = 0}):Play()
	local Shakes = script.ShakeScript:Clone()
	Shakes.Parent = game:GetService("Players").LocalPlayer.Character
	Shakes.Disabled = false
	game.Debris:AddItem(Shakes,3)	
end)

script.Parent.Equipped:Connect(function()
	if debounce == false then
		game:GetService('StarterGui'):SetCoreGuiEnabled(Enum.CoreGuiType.Backpack, false)
		task.wait(ToolBarHideTime)
		game:GetService('StarterGui'):SetCoreGuiEnabled(Enum.CoreGuiType.Backpack, true)
		track1:Stop()
	end
end)

but I don’t really know what that means and how to fix it.
can someone help me?

The wrap function in your case is possible to run only 1 time
Docs: coroutine | Documentation - Roblox Creator Hub
You can use something like this:

local function countdown()
	for i=Cooldown2, 0, -1 do
		script.Parent.Name = "Cooldown: ".. i
		task.wait(1)

		if i == 0 then
			script.Parent.Name = "Barrage"
			Cooldown2 = Cooldown
			debounce = false
		end
	end
end

task.spawn(countdown)

if you read the post title you would have seen its already solved (still thanks)

[bluebxrrybot (blueberry)]

You should post the solution you found, and then mark it as the solution. Maybe somebody else has the same problem you had?

[3YbuKtOp (Alex_Kornilov)]

Write then what is already solved and mark your message as solved so that the thread is closed.

function countdown()

coroutine.wrap(countdown)()
