Error while working with q sqlite table. What to do?

Question

Python

I have this code:

def pay(message):
    token = config.CONFIG['qiwi']
    phone = config.CONFIG['phone']
    db = sqlite3.connect('users.db')
    cursor = db.cursor()

    cursor.execute("""CREATE TABLE IF NOT EXISTS users (
        user_id TEXT,
        qrule TEXT,
        cash INTEGER,
        usersinbot INTEGER,
        pay TEXT,
        pay_money INTEGER
        
    )""")
    price = message.text
    api = QApi(token=token, phone=phone)
    if not price.isdigit():
        client.send_message(message.chat.id, 'Введите коректное значение')
        main(message)
        return
    price = int(price)
    
    comment = api.bill(price)
    cursor.execute(f"UPDATE users SET pay = {str(comment)} WHERE user_id = '{message.chat.id}'")
    db.commit()
    cursor.execute(f"UPDATE users SET pay_money = {price} WHERE user_id = '{message.chat.id}'")
    db.commit()
    
    markup_inline = types.InlineKeyboardMarkup()

    item_pay = types.InlineKeyboardButton(text = 'Оплатить', url='link_to_pay')
    item_check = types.InlineKeyboardButton(text = 'Проверить платёж', callback_data='check')
    item_back = types.InlineKeyboardButton(text = 'Назад', callback_data='bck')
    markup_inline.add(item_pay)
    markup_inline.add(item_check)
    markup_inline.add(item_back)
    client.send_message(message.chat.id, f'Для перехода к оплате нажмите кнопку оплатить и в комментариях к оплате оставьте код: {comment}. Если вы не оставите код то бот не примет платёж. В сумме для оплаты указывайте такое же число что вы отправили ранее.', reply_markup=markup_inline)

The comment variable stores a token for working with kiwi api.
An example token is 901ecc36-82fd-46ba-8792-9f40abe01319

And when I execute the pay function I get an error:

Traceback (most recent call last):

    cursor.execute(f"UPDATE users SET pay = {str(comment)} WHERE user_id = '{message.chat.id}'")
sqlite3.OperationalError: unrecognized token: "472f"

Why am I getting it and how can I fix it?
