MQTT lights are hidden for Google Home

I have Z-Wave lights connected to Fibaro HC3 gateway. Using official Home Assistant Add-on: Mosquitto broker and “Fibaro Home Center 3” to “Home Assistant” integration QuickApp (https://github.com/alexander-vitishchenko/hc3-to-mqtt) I have integrated lights from Fibaro to Home Assistant successfully and I am able to switch on/off and dime all of them in HA UI.

I am using Google Assistant integration (without Home Assistant Cloud) (https://www.home-assistant.io/integrations/google_assistant) and it works fine for all other devices except those connected via MQTT.

But I am not able to expose any device connected from Fibaro through MQTT.

My yaml configuration is simple:

google_assistant:
  project_id: home-assistant-xxxxx
  service_account: !include includes/service_account.json
  expose_by_default: false
  report_state: true

Is there some limitation for MQTT or other trick?

Please check documentation on ‘expose_by_default’.
And further…

Thank you for your comment. I am sorry, a copy paste mistake.

My current configuration for testing is

google_assistant:
  project_id: home-assistant-xxxx
  service_account: !include includes/service_account.json
  expose_by_default: true
  report_state: true

I don’t know if there is some relation with this, but in the log, there is one issue for the Google Assistant:
