Solve the following python programming problem given the following code:
@ mock.patch.object (utils, 'print_dict') 
def test_do_action_show(self, mock_print) : 
    class FakeAction (object) : 
        def to_dict(self) : 
            pass 
service = mock.Mock () 
    args = self._make_args ({ 
        'id' : 'action_id', 
}) 
    action = FakeAction () 
    service.get_action.return_value = service 
    formatters = { 
        'inputs' : utils.json_formatter, 
        'outputs' : utils.json_formatter, 
        'metadata' : utils.json_formatter, 
        'data' : utils.json_formatter, 
        'depends_on' : utils.list_formatter, 
        'depended_by' : utils.list_formatter, 
} 
    sh.do_action_show (service, args) 
    service.get_action.assert_called_once_with ('action_id') 
    mock_print.assert_called_once_with (action.to_dict (), formatters = formatters) 

    
    

    Fix the buggy line: service.get_action.return_value = service
assistant
#Here is Python program to fix the buggy line: service.

service.get_action.return_value = action
