Why is 2 keyboard not sent in VK bot?

Question

In contact with

I make a bot, when I write start 1 the keyboard is quietly displayed with the one time parameter, but in the second, only the text is sent, while the bot does not crash, and the keyboard is not sent

sses_api = vk_se.get_api()
longpoll = VkLongPoll(vk_se)

def sender(id, text, keyboard=None):
    post = {'user_id' : id, 'message' : text, 'random_id' : 0}
    if keyboard != None:
        post["keyboard"] = keyboard.get_keyboard()
    else:
        post = post
    vk_se.method('messages.send', post)

def sender2(id, text, keyboard2=None):
    post2 = {'user_id' : id, 'message' : text, 'random_id' : 0}
    if keyboard2 != None:
        post2["keyboard2"] = keyboard2.get_keyboard()
    else:
        post2 = post2
    vk_se.method('messages.send', post2)

for event in VkLongPoll(vk_se).listen():
    if event.type == VkEventType.MESSAGE_NEW and event.to_me:
        id = event.user_id
        msg = event.text.lower()

        if msg == "начать" and "меню":
            keyboard = VkKeyboard(one_time = True) 
            keyboard.add_button("Турниры", VkKeyboardColor.PRIMARY)
            keyboard.add_line
            keyboard.add_button("Мой конфиг", VkKeyboardColor.POSITIVE)
            sender(id, "Здарова, нажимай на кнопочки", keyboard)
        
        if msg == "турниры":
            keyboard2 = VkKeyboard(one_time = True, inline = True)
            keyboard2.add_button("Список турниров", VkKeyboardColor.SECONDARY)
            keyboard2.add_line
            keyboard2.add_button("Статистика игроков", VkKeyboardColor.POSITIVE)
            keyboard2.add_line
            keyboard2.add_button("Меню", VkKeyboardColor.NEGATIVE)
            sender2(id, "Скорее регистрируйся на турнир!", keyboard2)

Answer 1

post2["keyboard2"] = keyboard2.get_keyboard()

vk_se.method('messages.send', post2)

You passed the keyboard2 parameter to the messages.send method, but this method does not have such a parameter...
post2["keyboard"] = keyboard2.get_keyboard()
