Send text to telegram bot

I’m going crazy trying to solve this problem. I have an alarm that sends me a message to my cell phone and telegram bot indicating the sensor that caused the trigger.

Sending to mobile works fine and is as follows:

data:
  title: Antifurto
  message: |
     🚨 Allarme intervenuto per! 
     {{states('input_text.primo_sensore_attivato') }}
action: notify.mobile_app_myphone
enabled: true

I receive the sensor written in correctly: ‘input_text.primo_sensore_attivato’.
For the telegram bo I use this

data:
  title: ANTIFURTO
  message: | 
       🚨 Allarme 
          {{ states('input_text.primo_sensore_attivato')}}
action: notify.telegram
enabled: true

So nothing arrives on Telegram. If I remove the template from the telegram bot I get the message 🚨 Allarme but without the sensor that activated it.

I tried various examples found in the forum but without success. Do you have any suggestions for me?
thanks

What do the logs say in HA? Normally they say something when you have crappy format or something else.
