Websocket not giving any data

jhaanuj2108

I have created a sample code, and I am trying to run it to get live market data of SBIN, but it is only returning heartbeats, and no data is coming in.

from smartapi import SmartWebSocket

from smartapi import SmartConnect, SmartWebSocket


api_key = <api_key >
access_token = <access_token>

password = <password >
totp = pyotp.TOTP(access_token).now()
obj=SmartConnect(api_key=api_key)

ss = SmartWebSocket(FEED_TOKEN, CLIENT_CODE)

def on_message(ws, message):
    print("Ticks: {}".format(message))
    
def on_open(ws):
    print("on open")
    ss.subscribe(task,token)
    
def on_error(ws, error):
    print(error)
    
def on_close(ws):
    print("Close")

# Assign the callbacks.
ss._on_open = on_open
ss._on_message = on_message
ss._on_error = on_error
ss._on_close = on_close

ss.connect()




# ss.ws.close()
# obj.terminateSession(client_code)

The data contains my name and login information, so there is no problem generating a session, but the websocket doesn't give any data.

The only thing it returns is:

{'task': 'hb', 'channel': '', 'token': '0835520469', 'user': '<my_client_id>', 'acctid': '<my_client_id>'}
