I have created several Telegram bots. They work for my account and also on several other accounts that I have tested with.
But I get reports from several users saying the bots never respond.
It there some user setting that would prevent an account from getting messages from bots? Or any other idea why it would not work for some accounts?
Okay, found the issue, it was pebcak.
This issue was it was failing for users that had no last name set in their account because our code was accessing the last_name from the json data.
So make sure your code does not rely on a first or last name.
