Solve the following python programming problem given the following code:
@ defer.inlineCallbacks 
def test_EncodingJSONRPCServer(self) : 
    DATA = { 
        'foo' : 'bar', 
} 
    REQUEST = '{"jsonrpc": "2.0", "method": "test", "params": [], "id": 1}' 
    RESPONSE = (('{"jsonrpc": "2.0", "id": 1, "result": ' + json.dumps (DATA)) + '}') 
    class RPCServer (JSONRPCServer) : 
        def jsonrpc_test(self) : 
            return defer.succeed (DATA) 
class ReceiverProtocol (Protocol) : 
        def __init__(self, finished) : 
            self.finished = finished 
            self.body = [] 
def dataReceived(self, bytes) : 
            self.body.append (bytes) 
def connectionLost(self, reason) : 
            self.finished.callback (''.join (self.body)) 
class StringProducer (object) : 
        implements (IBodyProducer) 
        def __init__(self, body) : 
            self.body = body 
            self.length = len (body) 
def startProducing(self, consumer) : 
            consumer.write (self.body) 
            return defer.succeed (None) 
def pauseProducing(self) : 
            pass 
def stopProducing(self) : 
            pass 
server = RPCServer () 
    resource = EncodingJSONRPCServer (server) 
    site = Site (resource) 
    port = reactor.listenTCP (8888, site, interface = '127.0.0.1') 
    agent = ContentDecoderAgent (Agent (reactor), [('gzip', GzipDecoder)]) 
    response = (yield agent.request ('POST', 'http://127.0.0.1:8888', Headers ({ 
        'Accept-Encoding' : ['gzip'], 
}), StringProducer (REQUEST))) 
    self.assertTrue (isinstance (response, GzipDecoder)) 
    finished = defer.Deferred () 
    response.deliverBody (ReceiverProtocol (finished)) 
    data = (yield site) 
    self.assertEqual (data, RESPONSE) 
    port.stopListening () 

    
    

    Fix the buggy line: data = (yield site)
assistant
#Here is Python program to fix the buggy line: data = (yield site)
.

data = (yield finished)
