My animation only plays once what can be the problem?

Heres local script

local Player = game:GetService("Players")
local rp = game:GetService("ReplicatedStorage")
local Lancer = rp:WaitForChild("Lancer")

local UIS = game:GetService("UserInputService")

local debounce = false
local cooldown = 1

UIS.InputBegan:Connect(function(input,isTyping)
if isTyping then
	return
		
	elseif input.KeyCode == Enum.KeyCode.E and debounce == false then
	debounce = true

	Lancer:FireServer()
	

	
end
end)

Lancer.OnClientEvent:Connect(function()

	wait(cooldown)
	debounce = false
end)

And normal script

local rp = game:GetService("ReplicatedStorage")

local Lancer = rp:WaitForChild("Lancer")

local Animation = game.Workspace.Animations:WaitForChild("Swing")

	Lancer.OnServerEvent:Connect(function(Player) 

	  	  local Character = Player.Character 

	   	 local Humanoid = Character:FindFirstChild("Humanoid")

		    local LoadedAnimation = Humanoid:LoadAnimation(Animation)

	    LoadedAnimation:Play() 
	
end)

You are not firing the client once the animation has played, so the debounce never resets to false. Make sure to reset your debounce or else it will only work once.
