python - FIX sessionNotFound在启动时

我正在尝试使用quickfix构建我的修复应用程序，但是在启动它时，它会在登录之前先发送注销消息，并引发Session Not Found。

class Application(quickfix.Application):

def __init__(self, session, logger):        
    super(Application, self).__init__()
    self.session = session
    self.logger = logger

def onCreate(self, sessionID):
    self.logger.info("Created session {}.".format(sessionID))
    return
    
def onLogon(self, sessionID):
    self.logger.info("Logon session {}.".format(sessionID))      
    return 

def onLogout(self, sessionID):
    self.logger.info("Logout session {}.".format(sessionID))
    return

def toAdmin(self, message, sessionID):
    msgType = quickfix.MsgType()
    message.getHeader().getField(msgType)
    
    if msgType.getValue() == quickfix.MsgType_Logon:
        self.logger.info('LOGON SessionID {}'.format(sessionID))
    elif msgType.getValue() == quickfix.MsgType_Logout:
        self.logger.info('LOGOUT SessionID {}'.format(sessionID))
    
    self.logger.info('to Admin session {} send {}'.format(sessionID, self.messageToString(message)))
    self.session.sendToTarget(message)
    return

def toApp(self, message, sessionID):
    self.logger.info('to App: {}'.format(message))
    self.session.sendToTarget(message)
    return

def fromApp(self, message, sessionID):
    self.logger.info('from App: {}'.format(message))
    return

logger = create_logger(config)
settings = quickfix.SessionSettings(client_config)
application = Application(quickfix.Session, logger)
storeFactory = quickfix.FileStoreFactory(settings)
logFactory = quickfix.ScreenLogFactory(settings)
initiator = quickfix.SocketInitiator(application, storeFactory, settings, logFactory)
initiator.start()

我得到以下内容：

注销SessionID FIX44：Client-> Server到Admin会话FIX44：Client-> Server发送8 = FIX.4.4 | 9 = 62 | 35 = 5 | 34 = 26 | 49 = Client | 52 = 20200608-12：26：03 | 56 =服务器| 10 = 168

文件“ FIx.py”，第42行，位于toAdmin self.session.sendToTarget（message）SessionNotFound中：找不到会话

知道为什么它会引发信息吗？

谢谢大家！
