Solve the following python programming problem given the following code:
@ pytest.mark.parametrize ('serializer', ['json', 'pickle']) 
def test_event_serialization(container_factory, rabbit_config, sniffer_queue_factory, serializer) : 
    handler_called = Mock () 
    class Service (object) : 
        name = 'srcservice' 
        dispatch = EventDispatcher () 
        @ rpc 
        def dispatch_event(self, payload) : 
            self.dispatch ('eventtype', payload) 
@ event_handler ('srcservice', 'eventtype') 
        def handle_event(self, event_data) : 
            handler_called (event_data) 
rabbit_config [SERIALIZER_CONFIG_KEY] = serializer 
    container = container_factory (Service, serialized) 
    container.start () 
    get_messages = sniffer_queue_factory ('srcservice.events', routing_key = 'eventtype') 
    serialized = serialized_info [serializer] 
    with entrypoint_waiter (container, 'handle_event') : 
        with entrypoint_hook (container, 'dispatch_event') as dispatch_event : 
            dispatch_event (test_data) 
assert (handler_called.call_args == call (serialized ['data'])) 
    msg = get_messages () [0] 
    assert (msg ['properties'] ['content_type'] == serialized ['content_type']) 

    
    

    Fix the buggy line: container = container_factory (Service, serialized)
assistant
#Here is Python code to fix the buggy line: container = container_factory (Service, serialized)
.

container = container_factory (Service, rabbit_config)
