How to make response to node-telegram-bot-api request?

Question

JavaScript

when I do this, the response comes

bot.onText(/\/echo (.+)/, function (msg, match) {
    var chatId = msg.from.id; // Получаем ID отправителя
    var resp = match[1]; // Получаем текст после /echo
    bot.sendMessage(chatId, resp);
});

when i do it it doesn't work

bot.onText(/\/echo (.+)/, function (msg, match) {
    var chatId = msg.from.id; // Получаем ID отправителя
    var resp = match[1]; // Получаем текст после /echo
    var answer = 'пока!'
    bot.sendMessage(chatId, resp, answer);
});

Answer 1

Why should it work if the sendMessage method takes 3 arguments: chatId (string or number), text (string), [options] (object)
The 3rd argument is optional and must be passed as an object.
