Python3.x 使用 pythonbinance 时，heroku [regex._regex_core.error： bad escape \d at position 7] 出错

我试图在Heroku上上传我的python代码(Binance trade bot)，但出现了一个错误.谁能帮帮我吗？

from binance.client import Client
from datetime import datetime

client = Client(api,key)
symbol = 'IOSTUSDT'

for i in client.futures_historical_klines(symbol, Client.KLINE_INTERVAL_1MINUTE, '2022-03-16'):
    print(i)

错误是
