I have some weird cooldown when i launch a fireball, can someone help me fix this?

Hey guys, so I was following AlvinBlox's tutorial on how to make a fireball(https://www.youtube.com/watch?v=NIJqp5UuILg), and then when tutorial ended, i fixed weird curving by changing max force velocity from 5000 to math.huge. But, there is a problem that I have, and it isnt seen in Alvin's video, even tho our codes are almost same. When I press Q to launch a fireball, firstly it spawns, waits for ~1 second and only then launches. Here are the scripts:

--Script
local fireball = game.ServerStorage:WaitForChild("Fireball")

game.ReplicatedStorage.Fireball.OnServerEvent:Connect(function(player)
	
	local character = player.Character
	local newFireball = fireball:Clone()
	newFireball.CFrame = character.HumanoidRootPart.CFrame
	
	local bodyVelocity = Instance.new("BodyVelocity")
	bodyVelocity.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
	bodyVelocity.Velocity = (character.HumanoidRootPart.CFrame.lookVector*250)
	bodyVelocity.Parent = newFireball
	
	newFireball.Parent = workspace
	
	local touchConn
	
	touchConn = newFireball.Touched:Connect(function(hit)
		if hit.Parent:FindFirstChild("Humanoid") then
			if hit.Parent.Name ~= player.Name then
				hit.Parent:BreakJoints()
				if touchConn ~= nil then touchConn:Disconnect() end
				newFireball:Destroy()
				end
		end
	end)
	
	wait(2)
	
	if touchConn ~= nil then touchConn:Disconnect() end
	newFireball:Destroy()
	
end)

And Local Script.

--Local Script
local UserInputService = game:GetService("UserInputService")

local player = game.Players.LocalPlayer

local character = player.Character or player.CharacterAdded:Wait()

local debounce = false

UserInputService.InputBegan:Connect(function(Input , IsTyping)
	if not IsTyping then
		if not debounce then
			debounce = true
			
			if Input.KeyCode == Enum.KeyCode.Q then
				game.ReplicatedStorage.Fireball:FireServer()
				
			end
			
			wait(.001)
			debounce = false
		end
	end
end)

This is my first experience at these type of forums, so feel free to correct me if I did something wrong. Thank you all in advance.
