Adding cupboard auth list?

I'm trying to add players to cupboard with a command but keep getting "Add requires a non null target object" using:

Code:

playerSteamID = rust.UserIDFromPlayer(player)
    priv = global.BasePlayer._type:GetField("buildingPrivlidges", rust.PrivateBindingFlag())
    privb = priv:GetValue(player)
    for i = 0, privb.Count -1 do
        bldpriv[i].authorizedPlayers.Add(playerSteamID)
    end

What am I doing wrong or is it possible? Thanks.

 

Thanks. I'll take a look at it.

 

is removing a player's authorization just as simple as :

Code:

 priv.authorizedPlayers.Remove(new ProtoBuf.PlayerNameID()
                                    {
                                        userid = target.userID,
                                        username = target.displayName
                                    });
