Почему появляется ошибка 'list' object has no attribute 'to_dict'?

Здравствуйте! Пытаюсь создать инлайн-кнопки в цикле, разбивая их на ряды по 8 штук в каждом. Сами кнопки создаются, но клавиатура выдает ошибку: 'list' object has no attribute 'to_dict'. Подозреваю, что неправильно полльзуюсь методом keyboard.row(). Что я делаю не так?

def create_keyboard_details(buttons:list):
    print('\r\nКнопки:', buttons)
    #return None
    keyboard = types.InlineKeyboardMarkup()
    btns_in_row = 8
    keyboard.row_width = btns_in_row
    btn_count = len(buttons)
    row_count = btn_count//btns_in_row
    surplus = btn_count - row_count * btns_in_row
    print('\r\nКнопки в цикле:')
    for i in range(row_count):
        btn_list = []
        for N in range(btns_in_row):
            btn = types.InlineKeyboardButton(str(i * btns_in_row + N + 1), callback_data = 'pos_' + str(buttons[i * btns_in_row + N]))
            btn_list.append(btn)
        print(btn_list)
        keyboard.row(btn_list)
    btn_list = []
    for i in range(surplus):
        btn = types.InlineKeyboardButton(str(btn_count - surplus + i), callback_data = 'pos_' + str(buttons[btn_count - surplus + i]))
        btn_list.append(btn)
    print(btn_list)
    keyboard.row(btn_list)
    return keyboard

Результат в консоли:

Кнопки в цикле:
