why will an in game negate operation with a SubtractASync() not work!!!???

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
