Telegram Bot Fails booting

Looks like after the upgrade from the 0.44 telegram has stopped working (fotìr me at last).

This is the error log:

And this is the configuration:

  platform: telegram
  api_key: mykey
  chat_id: oneid

I’ve already checked the deps and this bug:

But no workaround seems to work

My bad, now the bot requires the polling configuration
