[SOLVED] Notify.telegram stopped working

Hey there,

did something change regarding the notify.telegram-component? It stopped working for me since release 0.72.
I just added a new notification with the following setup:

configuration.yaml:

notify:
  - name: Telegram_Haushalt
    platform: telegram
    chat_id: CHATID

automations.yaml

- id: 'telegramgeburtstage'
  alias: 'Telegram Erinnerung an Geburtstage'
  trigger:
  - entity_id: sensor.telegram_geburtstage
    platform: state
    to: 'on'
  condition: []
  action:
  - service: notify.telegram_haushalt
    data_template:
      message: 'Heute hat {{ states.calendar.geburtstagskalender.attributes.message }} Geburtstag.'

log, if automation gets manually triggered:

DEBUG (SyncWorker_1) [homeassistant.components.notify.telegram] TELEGRAM NOTIFIER calling telegram_bot.send_message with {'target': CHATID, 'message': 'Heute hat xyz Geburtstag.'}

So basically the log says message sent but nothing arrives at Telegram? The CHATID is entered correctly. I also tested it with another CHATID. Didn’t work.

Strange: Some time ago I’ve set up some alerts (also sent via telegram) - they’re still working fine.

Any ideas?

Thanks in advance!

Solved by myself:

Problem was the output of the string:

{{ states.calendar.geburtstagskalender.attributes.message }}

which involved a symbol python apparently wasn’t able to handle. Removing the symbol solved the issue.
