Unable to send TTS to Alexa via notifications

Configuration Voice Assistant
1

I keep receiving errors when trying to send a TTS notification to my Office Alexa device via the following yaml entered in the Developer Tools service section. I’m new to Home Assistant so am probably doing something silly. I’m using the Nabucasa cloud to connect to Alexa and I can send TTS successfully if I use the Mini Media Player. I have recently migrated from a Raspberry Pi 4 to a Optiplex 7090 so I am not sure if this has something to do with it.

Thanks for any help

service: notify.alexa_media_office
data:
  message: The garage door has been open for 10 minutes.
  title: Your Garage Door Friend
  target: 
  data: tts

This is the error I am seeing when I press the “Call Service” button

Mine looks like this :

service: notify.alexa_media
data_template:
  target:
    - media_player.office_flex
  data:
    type: announce
  message: >-
    System Issue Logged, {{
    states.sensor.zabbix_alerts.attributes.subject.split(':')[1] }}.

Thanks very much Neil, I was missing the ‘type’ under the data parameter, the following now works

service: notify.alexa_media_office
data:
  message: The garage door has been open for 10 minutes.
  data:
    type: tts
