That's Telegrams fault afaik.

[vbauer]

Probably, but is it possible to wrap this exception? In the current moment my bot suddenly breaks.

[derhuerst]

Why would you wrap that error? I think it is your responsibility you properly handle that error.

[vbauer]

I mean this error occurs in the part of node-telegram-bot library. Is it possible to handle somehow this exception in my code?

[derhuerst]

How do you receive the error?

[vbauer]

You can see full stacktrace in the description. That's all I have..

[derhuerst]

Did you get it in a callback or has it been thrown somewhere else?

[vbauer]

If I have got this information, I could catch this error and add some logging, but I do not know how to understand it using this stacktrace.

I see that error occurs somewhere in poll method inside pollingRequest: https://github.com/depoio/node-telegram-bot/blob/master/lib/Bot.js#L273

[derhuerst]

Do something like bot.on('error', (err) => {/* handle error here */).

[vbauer]

Thank you for suggestion, I will try it as soon as possible!

[vbauer]

Hmm.. I've just checked source and I already have the following code (but bot was stopped anyway).

bot.on('error', function (error) {
    log(error);
});

Perhaps the problem was caused by OpenShift. Thank you for your time! I will reopen this ticket, if find something interesting.
