Configure Google assistent and garage doors

Hi!
I have added the Google assistent to HA. One of the reason is to be able to control my garage doors.
Everything seems fine in HA and in Google Home. But when I ask Google assistent to open my left (or right) garage door, I only get a reply, telling med it requires a password and that isn’t configured yet. It’s all in swedish, so I can’t give you the exact message.
In my configuration.yaml I have added:

google_assistant:
  project_id: my_project_id
  api_key: my_api_key
  service_account: !include service_account.json
  report_state: true
  exposed_domains:
    - cover

I also have a service_account.json file stored.

What am I missing? Thanks and merry christmas!

I’ve now added the line:
secure_devices_pin: xxxx

That makes an error in the configuration. Please help!

I found the solution. The pincode must have " ". Eg.
secure_devices_pin: “1234”.
