Why my raycast isn't work?

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local SoundService = game:GetService("SoundService")

local shootEvent = ReplicatedStorage.Events.ShootEvent

local shootSound = SoundService.ShootSound

local function onShootEvent(player, mousePosition: Vector3, shootCursorPosition: Vector3)
	local direction = (mousePosition - shootCursorPosition)
	local result = workspace:Raycast(shootCursorPosition, direction)
	
	shootSound:Play()
	
	if result then
		print(result.Instance)
		local humanoid = result.Instance.Parent:FindFirstChild("Humanoid"):: Humanoid
		
		if humanoid then
			humanoid:TakeDamage(10)
		end
	end
end

shootEvent.OnServerEvent:Connect(onShootEvent)

@Rewlaxe

(mousePosition - shootCursorPosition)

It should be (mousePosition - shootCursorPosition).Unit.
Also, you should just raycast on the client and then send the results to the server for processing.
