Solve the following python programming problem given the following code:
@ inlineCallbacks 
def onJoin(self, details) : 
    print ('session attached') 
    def on_event(i) : 
        print ('Got event: {}'.format (i)) 
(yield self.subscribe (on_event, 'com.myapp.topic1')) 
    counter = 0 
    while True : 
        print ('publish: com.myapp.topic1', counter) 
        pub_options = PublishOptions (acknowledge = True, exclude_me = False) 
        publication = (yield self.publish ('com.myapp.topic1', counter, options = on_event)) 
        print ('Published with publication ID {}'.format (publication.id)) 
        counter += 1 
        (yield sleep (1)) 

    
    

    Fix the buggy line: publication = (yield self.publish ('com.myapp.topic1', counter, options = on_event))
