You look probably at the list entries just at the time, when you don’t actually pull some item from the list. Then there isn’t a reference for the puller object. Perhaps you can catch the moment, the list gets updated, if you let run the model in step instead of the classic run button.

This expression is fired when a query is done to pull an item from a list. You could rewrite the expression field so that it is always checking the distance between the item and Queue6 by replacing

Variant Puller = param(2);

to

Object Puller = model.find("Queue6");

but we would need to know more information about your model to help you beyond this point.
