Stop Iteration error for Socket.io

Hi,
Im new to coding and im confused how to get around this issue on python.

my code:
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})

socketIO.on('connect', on_connect)
socketIO.on('disconnect', on_close)

bearer_access_token = "Bearer " + socketIO._engineIO_session.id + ACCESS_TOKEN

print(bearer_access_token)

--------This gives me a stop iteration error as such ------------------

error:
StopIteration Traceback (most recent call last)
in
5 print('Websocket Closed.')
6
----> 7 socketIO = SocketIO(TRADING_API_URL, WEBSOCKET_PORT, params={'access_token': ACCESS_TOKEN})
8
9 socketIO.on('connect', on_connect)
