what i want to do is make a kind of "hole puncher" sniper by subtracting the beam to the part that is being shot at. however, it doesn't work and the output says "Attempt to connect failed: Passed value is not a function".

here is the function to punch the hole

a script in serverScriptService

negatePartRemoteFunction.OnServerInvoke = function (beam,part,player)
	local success, punchedPart = pcall(function()
		return part:SubtractAsync({beam})
	end)
	
	if success then
		print("The union operation is successful.")
	end
	
	if success and punchedPart then
		punchedPart.Position = part.Position
		punchedPart.Anchored = true
		punchedPart.Name = part.Name
		punchedPart.Parent = part.Parent
		part:Destroy()
		print("The replacement is successful.")
		negateSuccess:FireClient(player)
	end
end
