Solve the following python programming problem given the following code:
def setUp(self) : 
    self.registry = CollectorRegistry () 
    self.data = '' 
    class TCPHandler (SocketServer.BaseRequestHandler) : 
        def handle(s) : 
            self.data = s.request.recv (1024) 
server = SocketServer.TCPServer (('', 0), TCPHandler) 
    class ServingThread (threading.Thread) : 
        def run(self) : 
            server.handle_request () 
            server.socket.close () 
self.t = ServingThread () 
    self.t.start () 
    address = ('localhost', self.server_address [1]) 
    self.gb = GraphiteBridge (address, self.registry, _time = FakeTime ()) 

    
    

    Fix the buggy line: address = ('localhost', self.server_address [1])
