Error in log with telegram conf

Hi. I’m going crazy.I have two errors in the HA log. I have read from documentation but my configuration is the one suggested in it.
My Home Assistant version is 0.90.2 and my raspbian version is stretch. This is the link:

my log:

2019-08-23 13:49:28 ERROR (Thread-2) [homeassistant.util.yaml] YAML file /home/homeassistant/.homeassistant/configuration.yaml contains duplicate key "chat_id". Check lines 285 and 286.
2019-08-23 13:49:28 ERROR (Thread-2) [homeassistant.util.yaml] YAML file /home/homeassistant/.homeassistant/configuration.yaml contains duplicate key "chat_id". Check lines 286 and 287.

my configuration.yaml:

telegram_bot:
  - platform: polling
    api_key: mykey
    allowed_chat_ids:
      - 111111111 
      - 222222222
      - 333333333

notify:
  - name: notificatore_telegram
    platform: telegram
    chat_id: 111111111# line 285
    chat_id: 222222222#line 286
    chat_id: 333333333#line 287

Every suggestion is welcome. Thanks

If you want MULTIPLE chats, you have to create MULTIPLE notify sections

notify:
  - name: notificatore_telegram1
    platform: telegram
    chat_id: 111111111# line 285
  - name: notificatore_telegram2
    platform: telegram
    chat_id: 222222222#line 286
  - name: notificatore_telegram3
    platform: telegram
    chat_id: 333333333#line 287

Hi flamingm0e.
With your suggestion it worked. There are no more errors in the log. But is the documentation wrong?

Not at all. What part do you think is incorrect?

Hi flamingm0e. Thank you for your answer. I apologize but re-reading the documentation and reflecting on your answer I realized that I did not understand what the documentation said.I recently started using HA and I still have to experience. Sorry
