TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'

When I try on new crypto, coingecko return null value in market cap.

My workaround in telegram_crypto_price_bot/utils/utils.py change block line 63 to :

    # Convert string to integer
    @staticmethod
    def StrToInt(s: str) -> int:
        if s is None:
            res = int(0)
        else:
            res = int(s)
        return res
