[Bug] Unable to get Websockets to work

[anshulmittal712]

Description I'm trying to follow the example as mentioned here to subscribe to a few tickers but I don't get any events. I understand that WS are only for paid plans and I am still evaluating it on the Basic plan, but as per the documentation and this support link, there are a few instruments for which the trial for WS is enabled even for the base users, with certain limitations. I have tried with multiple tickers from this list, and also from the ones in the example, but to no avail.

My code

from twelvedata import TDClient
import os
td = TDClient(apikey=os.getenv("TD_API_KEY"))

ts = td.time_series(
    symbol="BTC/USD",
    interval="1min",
    outputsize=1
).as_json()
print(ts)

def on_event(e):
    print(e)

ws = td.websocket(symbols=['BTC/USD'], on_event=on_event, log_level="debug")
ws.subscribe(['ETH/BTC', 'AAPL','BTC/USD'])
ws.connect()
ws.keep_alive()

Expected Output and Problem Description To establish that the API key works, I am printing the Time Series for BTC/USD. That works as expected. However, the second part of the code does not add any tickers to the list of subscribed instruments.

I am expecting at least an output like so, (and then the subsequent events for change in ticker price):

{"event":"subscribe-status","status":"ok","success":[{"symbol":"BTC/USD","exchange":"Binance","country":"","type":"Digital Currency"}],"fails":null}

Screenshots of actual output The output just stays at this and I need to interrupt to exit from this.

Thanks a lot, @midasSSS. Spent hours pouring over source code trying to see what's going wrong, and this simple dependency change fixes it. 🥳 🎊

Might be useful to include this in the Readme here. Can raise a PR for the same.
