Telegram parser bot not working on Heroku?

Question

Bots

I uploaded the bot to heroku, all the necessary libraries were installed, but the function below does not want to run, although when the bot is launched on a PC, everything works fine, tell me what could be the problem?

def asos_parser_bot(linksJs, all_urls, headers, valuet, session, soup):
    goods = []
    conuntryList = ['RU', 'GB', 'AU', 'TW', 'HK', 'IL', 'CN', 'TR', 'DE', 'SE', 'FR', 'EE']
    for i in range(len(all_urls)):

        country = conuntryList[i]

        requestPrice = session.get(linksJs[i], headers=headers)
        soupJs = bs(requestPrice.content, 'lxml')
        soupJs = str(soupJs)
        root = etree.fromstring(soupJs)
        price = json.loads(root.xpath('.//p')[0].text)
        price = price[0]['productPrice']['current']['value']

        if i == 1:
            name = soup.find('h1').text
            goods.append({'name': name})

        goods.append({
            'country': country,
            'price': float(price),
            'valuet': valuet[i],
            'url': all_urls[i]
            })
    return goods

the code before and after this function also works properly on heroku, all libraries (except json) that are used in this function are used in others
