Hey I'm trying to add my bot to a group (even with bot group enabled in botfather) but I get this issue:

Traceback (most recent call last):
    8: from test.rb:5:in `<main>'
    7: from /home/pi/.rvm/gems/ruby-2.5.0/gems/telegram-bot-ruby-0.8.6.1/lib/telegram/bot/client.rb:8:in `run'

I remember it used to work in the past but for some reasons it's not anymore, I'm using the code example you mentioned in the README.md:

require 'telegram/bot'

token = 'YOUR_TELEGRAM_BOT_API_TOKEN'

Telegram::Bot::Client.run(token) do |bot|
  bot.listen do |message|
    case message.text
    when '/start'
      bot.api.send_message(chat_id: message.chat.id, text: "Hello, #{message.from.first_name}")
    when '/stop'
      bot.api.send_message(chat_id: message.chat.id, text: "Bye, #{message.from.first_name}")
    end
  end
end

this is the error when I update the library to the latest version instead:

Traceback (most recent call last):
    8: from test.rb:5:in `<main>'

Hey @syxanash,

You need to check message type first, see https://github.com/atipugin/telegram-bot-ruby/issues/226#issuecomment-797296565
