in my code I wrote
` // error handler (avoid spam in console)
telegram.on('polling_error', function(error) {});
telegram.on('webhook_error', function(error) {});
`
to prevent my log to get flooded but they didn't caught these errors.
Is there any way to catch these errors?
Probably the telegram servers were down and the bot tried to poll them.
thanks guys!!
