How to detect a Model in ServerStorage with a Server Script Service script?

Hi, I am trying to find a Model in ServerStorage. I am doing :FireServer("FishingMachine") in a Local Script in StarterGui, and the server script detects the OnServerEvent and trys to find the "FishingMachine" in serverstorage. I am trying this by doing this:

local Event = game.ReplicatedStorage.GiveDropper
Event.OnServerEvent:Connect(function(data)
	if game.ServerStorage:FindFirstChild(data.Name) then
		print("Found")
		local Cloned = game.ServerStorage:FindFirstChild(data.Name):Clone()
		Cloned.Parent = game.Workspace
	end
end)

In the script that fires the event, it looks like this:

 local  Button = game.Workspace.Button
	local Gui = game.Players.LocalPlayer.PlayerGui:WaitForChild("MainGui"):WaitForChild("NoCash")
	local Event = game.ReplicatedStorage.GiveDropper
game.Workspace.Button.Touched:connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		local Cash = game.Players.LocalPlayer:FindFirstChild("leaderstats"):FindFirstChild("Cash")
		if Cash.Value >= 50 then
			Button:Destroy()
			Cash.Value = Cash.Value - 50
			game.Workspace.BoughtSound:Play()
			Event:FireServer("FishingMachine")
			print("Fired")
			else
			Gui.Visible = true
			wait(1.2)
			Gui.Visible = false
		end
	end
end)
		

Ive tried this:

local Event = game.ReplicatedStorage.GiveDropper
Event.OnServerEvent:Connect(function(player,data)
    if game.ServerStorage:FindFirstChild(data.Name) then
        print("Found")
        local Cloned = game.ServerStorage:FindFirstChild(data.Name):Clone()
        Cloned.Parent = game.Workspace
    end
end)

but says 'Argument 1 missing or nil' in the Output. It doesnt seem to find it. What else should i try and do?? I have checked for spelling mistakes and found none, in the script and the Model in ServerStorage. Thanks.

When receiving an event from the client the first parameter will always be the player, so your server function would be:

local Event = game.ReplicatedStorage.GiveDropper
Event.OnServerEvent:Connect(function(player,data)
    if game.ServerStorage:FindFirstChild(data.Name) then
        print("Found")
        local Cloned = game.ServerStorage:FindFirstChild(data.Name):Clone()
        Cloned.Parent = game.Workspace
    end
end)
