NullReferenceException help.

Code:

    public class itemQueue : RustPlugin{
        public BasePlayer player;
        public SpecialQueue<ItemCraft> queue;
       
        public itemQueue(BasePlayer ppl) {
            this.player = ppl;
            this.queue = new SpecialQueue<ItemCraft>();
           
            loopQueue();
        }
       
        public void addItem(ItemCraft item){
            this.queue.Enqueue(item);
        }
       
        public void remItem(ItemCraft item){
            this.queue.Remove(item);
        }
       
        public void dQu_Item(){
            this.queue.Dequeue();
        }
       
        public void loopQueue(){
            timer.Repeat(1f, 0, () =>
            {
                rust.BroadcastChat("TEST");
            });
        }
    }

When this code runs whenever rust.BroadcastChat("TEST"); is ran it throws this error.

03:04 [Error] Failed to run a 1.00 timer in 'itemQueue v1.0.0' (NullReferenceException: Object reference not set to an instance of an object)

Any idea why?

 

Solved.
