Issue sending pictures with telegram

Hello,
I am trying to send a photo to my telegram group configuration as follow:

Running Docker version supervised on Debian server:
Version core-2021.1.5
Version supervisor-2021.01.7

configuration.yaml

  whitelist_external_dirs: 
    - /config/pics
    - /tmp/snapshots

# TELEGRAM
telegram_bot:
 - platform: polling
   api_key: {removed}
   allowed_chat_ids:
    - {removed}

# TELEGRAM group
notify:
 - platform: telegram
   name: notifygrp
   chat_id: {removed}

picture is located

bash-5.0# ls
community     lastsnap.jpg  snapshots
bash-5.0# pwd
/config/www

and

bash-5.0# ls
lastsnap.jpg
bash-5.0# pwd
/tmp/snapshots

this is the automation:

alias: Motion detected
description: ''
trigger:
  - type: motion
    platform: device
    device_id: cbc562c863bac9dae8df28057d3b5e06
    entity_id: binary_sensor.cam_motion
    domain: binary_sensor
condition: []
action:
  - service: telegram_bot.send_message
    data:
      message: '{{now().strftime("%d.%m.%Y-%H:%M")}}'
  - service: telegram_bot.send_photo
    data:
      data:
        file: /tmp/snapshots/lastsnap.jpg
  - service: telegram_bot.send_photo
    data:
      data:
        file: /config/www/lastsnap.jpg
mode: single

the message with the date gets delivered but the pictures don’t and I get in the log the following:

2021-02-01 19:12:32 WARNING (SyncWorker_0) [homeassistant.components.telegram_bot] Can't load data. No data found in params!

Any advice?
