Solve the following python programming problem given the following code:
def test_drain_events_unregistered_queue(self) : 
    c1 = self.c.channel () 
    producer = self.c.Producer () 
    consumer = self.c.Consumer ([self.q2]) 
    producer.publish ({ 
        'hello' : 'world', 
}, declare = producer.queues, routing_key = self.q2.routing_key, exchange = self.q2.exchange) 
    message = consumer.queues [0].get ()._raw 
    class Cycle (object) : 
        def get(self, timeout = None) : 
            return ((message, 'foo'), c1) 
self.c.transport.cycle = Cycle () 
    self.c.drain_events () 

    
    

    Fix the buggy line: }, declare = producer.queues, routing_key = self.q2.routing_key, exchange = self.q2.exchange)

#Here is Python code to fix the buggy line: }, declare = producer.
