Iteration Error

Hi all

I am writing code to try to use socketIO but it returns with "IterationStop". My code is as follows:

import pandas as pd
import json
import requests
from socketIO_client import SocketIO

TRADING_API_URL = 'https://api.abc.com:443'
WEBSOCKET_PORT = 443
ACCESS_TOKEN = '123456789'

def on_connect():
print('Websocket Connected: ' + socketIO._engineIO_session.id)
def on_close():
print('Websocket Closed.')
socketIO = SocketIO(TRADING_API_URL, WEBSOCKET_PORT, params={'access_token': ACCESS_TOKEN})

Here is the error. Grateful if anyone can help. I am new to programming. Thanks.
