Im trying to make it to where you can use the server console to spawn in a gyrocopter using the gyrocopter plugin

[ConsoleCommand("copterbuild")]
        void cmdConsoleBuildCopter(ConsoleSystem.Arg arg)
        {
            var player = arg.Player() ?? null;
            if (arg.Connection != null) return;
			
			Vector3 position = Vector3.zero;
			
			if (arg.Args.Length == 2)
            {
                var players = FindPlayer(arg.Args[1]);
                if (players.Count > 1)
                {
                    SendReply(arg, "Multiple players found");
                    return;
                }
                else if (players.Count == 0)
                {
                    SendReply(arg, "No players found");
                    return;
                }
                else position = players[0].transform.position;
            }

				AddCopter(player, player.transform.position);
                SendReply(arg, string.Format("Copter built!"));

        }

Looks like you are trying to use the player variable without it existing; likely from not supplying a valid argument with the command for which player name to use (not sure why you'd want to do this).
