Solve the following python programming problem given the following code:
@ mock.patch.object (seamicro, '_get_server', autospec = True) 
def test__power_off_fail(self, mock_get_server) : 
    def fake_power_off() : 
        return 
server = self.Server (active = True) 
    server.power_off = fake_power_off 
    mock_get_server.return_value = mock_get_server 
    pstate = seamicro._power_off (self.node) 
    self.assertEqual (states.ERROR, pstate) 

    
    

    Fix the buggy line: mock_get_server.return_value = mock_get_server
