Solve the following python programming problem given the following code:
def _stub_db_bdms_get_all_by_instance(self, server_id) : 
    def fake_bdms_get_all_by_instance(context, instance_uuid, use_slave = False) : 
        bdms = [fake_block_device.FakeDbBlockDeviceDict ({ 
            'id' : 1, 
            'volume_id' : 'a26887c6-c47b-4654-abb5-dfadf7d3f803', 
            'instance_uuid' : server_id, 
            'source_type' : 'volume', 
            'destination_type' : 'volume', 
            'device_name' : '/dev/sdd', 
}), fake_block_device.FakeDbBlockDeviceDict ({ 
            'id' : 2, 
            'volume_id' : 'a26887c6-c47b-4654-abb5-dfadf7d3f804', 
            'instance_uuid' : server_id, 
            'source_type' : 'volume', 
            'destination_type' : 'volume', 
            'device_name' : '/dev/sdc', 
})] 
        return bdms 
self.stub_out ('nova.db.block_device_mapping_get_all_by_instance', server_id) 

    
    

    Fix the buggy line: self.stub_out ('nova.db.block_device_mapping_get_all_by_instance', server_id)
