Ошибка итерации запроса на Bi-directional stream для получения биржевой информации по Tinkoff Invest API

Мое торговый бот имеет функцию, которая должна запрашивать данные с биржи в реальном времени с помощью Tinkoff Invest API. В API это делается с помощью сервиса MarketDataStreamService. Стрим принимает запрос как аргумент-итератор, и возвращает объект-итератор. В моем случае запрашиваются пятиминутные свечи по акциям Сбера. Вот как это выглядит:

@bot.message_handler(commands=['get_data_stream'])
def getCandlesDataStream(message):


    def request_iterator():
        yield schemas.MarketDataRequest(
            subscribe_candles_request=schemas.SubscribeCandlesRequest(
                waiting_close=True,
                subscription_action=schemas.SubscriptionAction.SUBSCRIPTION_ACTION_SUBSCRIBE,
                instruments=[
                    schemas.CandleInstrument(
                        figi='TCS009029540',
                        interval=schemas.SubscriptionInterval.SUBSCRIPTION_INTERVAL_FIVE_MINUTE,
                    )
                ],
            )
        )
        while True:
            time.sleep(1)

    with SandboxClient(TOKEN) as client:             # Запускаем клиент тинькофф-песочницы
        for marketdata in client.market_data_stream.market_data_stream(
            request_iterator()
        ):
            print(marketdata)

Импорты:

from tinkoff.invest import CandleInterval
from tinkoff.invest import schemas

# Для исторических свечей
from tinkoff.invest.services import MarketDataCache, MarketDataStreamService
from tinkoff.invest.caching.market_data_cache.cache_settings import (
    MarketDataCacheSettings,
)

При вызове функции MarketDataStream, при попытке инициализации итератора вызывается ошибка итерации. Вот Traceback:

ERROR:grpc._channel:Exception iterating requests!

The above exception was the direct cause of the following exception:

Насколько я понял, ошибка в том, что нет какой-то мета информации. Возможно я ошибаюсь. Помогите разобраться
