Solve the following python programming problem given the following code:
def _stop_gateway_vpn_connections(context, neutron, cleaner, vpn_gateway) : 
    def undo_vpn_connection(context, vpn_connection, connections_ids) : 
        vpn_connection ['os_ipsec_site_connections'] = connections_ids 
        db_api.update_item (context, vpn_connection) 
for vpn_connection in db_api.get_items (context, 'vpn') : 
        if (vpn_connection ['vpn_gateway_id'] == vpn_gateway ['id']) : 
            _stop_vpn_connection (neutron, vpn_connection) 
            connection_ids = vpn_connection ['os_ipsec_site_connections'] 
            vpn_connection ['os_ipsec_site_connections'] = { 
                
} 
            db_api.update_item (context, vpn_connection) 
            cleaner.addCleanup (undo_vpn_connection, cleaner, vpn_connection, connection_ids) 

    
    

    Fix the buggy line: cleaner.addCleanup (undo_vpn_connection, cleaner, vpn_connection, connection_ids)
