bot = fut.Core(...)
count = 0
while count < 100:
    bs = bot.search(...)
    for x in bs:
        flag = bot.bid(x['tradeId'], 200, fast=True)
        print(flag)
        if flag:
            bot.sendToClub(x['id'])
            count += 1
            print("count:%d" % (count))
...

does anyone know how to avoid this error?

yes, it is an error when the trade is expired or the tradeid is invalid.

[tosssman]

search_result = bot.search(...)[1:random.randint(4, 6)]

time.sleep(60)

It works for me
