Hi, when i want to configure Telegram bot, i have this error :

v3.0.0 Unhandled error, please open a Github issue so we can fix it!
  File "/usr/src/app/modules/Logger.py", line 168, in notify
    send_notification(msg, notify_conf)
  File "/usr/src/app/modules/Notify.py", line 127, in send_notification
    post_to_telegram(msg, nc['telegram_chat_ids'], nc['telegram_bot_id'])
  File "/usr/src/app/modules/Notify.py", line 59, in post_to_telegram
    raise NotificationException("{0}\n{1}".format(e, msg))
modules.Notify.NotificationException: HTTP Error 400: Bad Request
Your bot id is probably configured incorrectly

And the cfg :

telegram = True
telegram_bot_id = 547xxxxxx:XXXXxxxXXXxxxxBoxP0Ws3xxxxxxxxxxx
telegram_chat_ids = @xxLendingxxxxxx

Thk :)
