Ломается при вводе команды /hadis в телеграмм боте

Что бы код бота работал нужно изменить код:

import requests
import random
import telebot
from bs4 import BeautifulSoup as bs

headers = {
'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:55.0) Gecko/20100101

    soup = bs(r.text, 'html.parser')
    hadises = soup.find_all('h1', class_='entry-title')
    return [c.link for c in hadises]

hadis_list = parser(URL, )
random.shuffle(hadis_list)

bot = telebot.TeleBot(API)

    del hadis_list[0]

@bot.message_handler(content_types=['text'])

    bot.send_message(mess.chat.id, 'Введите команду "/Hadis"')
if __name__ == '__main__':
    bot.polling(non_stop=True)
