[frenchthibaut]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

`import logging
import config

from alpaca_trade_api.stream import Stream

log = logging.getLogger(name)

async def print_trade(t):
print('trade', t)

async def print_quote(q):
if q["x"] == "FTXU":
print('quote', q)

async def print_trade_update(tu):
print('trade update', tu)

async def print_crypto_trade(t):
print('crypto trade', t)

def main():
logging.basicConfig(level=logging.INFO)
feed = 'iex' # <- replace to SIP if you have PRO subscription
stream = Stream(key_id=config.API_KEY,secret_key=config.SECRET_KEY,data_feed=feed, raw_data=True)
stream.subscribe_trade_updates(print_trade_update)
stream.subscribe_trades(print_trade, 'AAPL')
stream.subscribe_quotes(print_quote, 'IBM')
stream.subscribe_crypto_trades(print_crypto_trade, 'ETHUSD')
stream.subscribe_crypto_quotes(print_quote, 'ETHUSD')

@stream.on_bar('MSFT')
async def _(bar):
    print('bar', bar)

@stream.on_updated_bar('MSFT')
async def _(bar):
    print('updated bar', bar)

@stream.on_status("*")
async def _(status):
    print('status', status)

@stream.on_luld('AAPL', 'MSFT')
async def _(luld):
    print('LULD', luld)

stream.run()

if name == "main":
main()
`

Expected Behavior

In the provided example, all functions work as expected but "stream.subscribe_trade_updates".
It gives the following error:

INFO:alpaca_trade_api.stream:started trading stream
INFO:alpaca_trade_api.stream:starting trading websocket connection
ERROR:alpaca_trade_api.stream:error during websocket communication: failed to authenticate

SDK Version I encountered this issue in
