Question

Why error? ```const bot = new TelegramBot(token, {polling: true}); bot.on('audio', (msg)

=> {

var path = bot.downloadFile(msg.audio[msg.audio.length-1].file_id, ".").filePath;
console.log(path);
const chatId = msg.chat.id;
bot.sendMessage(chatId, 'Received your audio ${path}');
});
bot.on('message', (msg) => {
const chatId = msg.chat.id;

// send a message to the chat acknowledging receipt of their message
bot.sendMessage(chatId, 'Received your message');
});```
