Node-telegram-bot-api: error: [polling_error] {}

[roodx5]

var TelegramBot = require('node-telegram-bot-api');
var token = '';

const bot = new TelegramBot(token, {polling:true});
bot.onText('message',function(msg) {

var text = msg.text;
var chatId = msg.chat.id;
var type = msg.chat.type;
var userid = msg.from.id;

if(text == "id"){
bot.sendMessage(chatId+"chtid");

}
});

var opt = {polling:true};

var bot = new Telegram(token,opt);

Add a listener in your code like:

bot.on("polling_error", console.log);

It is probably a syntax error in your code. Something undefined or such that makes crash your program.

I also had the same problem. After adding a listener like @alexandercerutti mentioned I got the following exception:

To solve this I changed the regexp value from string to a RegExp object, which solved the problem for me. If you've the same error you've to change your call to the following:

bot.onText(RegExp('message'), function(msg) {

I hope this helps ;)

Edit: You can also just remove the ' Semicolon

[alexandercerutti]

@McCrafterIV Can you show what you wrote instead of the RegExp object? Because I've never seen that error happening.

[alexandercerutti]

Oh freak! I've seen now, in that unformatted piece of code in the first message, that the problem is, of course, the fact that it is being used the method onText with a string as parameter instead of a Regex. I think that happened too to you @McCrafterIV. Can you confirm?

I've basically removed the quotes and added a valid regex "string":
bot.onText(RegExp(/message/), function(msg) {

Right that was my problem

[alexandercerutti]

Of course it was failing. Because it was trying to call exec method on a non-Regex Object (strings don't have it). You can also write just /message/, without using RegExp object.

bot.onText(/message/, (msg) => { ... });
