[exposed_domians] is an invalid option for [google_assistant]

hi folks

I try to integrate the google_assistant to my homa assistant an get this error by checking my serverconfiguration:

[exposed_domians] is an invalid option for [google_assistant]. Check: google_assistant->google_assistant->exposed_domians.

my google_assistant configuration looks like this:

project_id: test-d912a
service_account:
    private_key: "-----BEGIN PRIVATE KEY-----\n-----END PRIVATE KEY-----\n"
    client_email: "            .iam.gserviceaccount.com"
report_state: true
exposed_domians:
    - switch
    - light
    - scene
    - script
    - camera
    - sensor

what the hell is wrong?

thanks for help

This exposed_domians: should be exposed_domains:
Also, make sure all the indentation are correct by following the example in the documentation-

google_assistant:
  project_id: YOUR_PROJECT_ID
  service_account: !include SERVICE_ACCOUNT.JSON
  report_state: true
  exposed_domains:
    - switch
    - light
  entity_config:
    switch.kitchen:
      name: CUSTOM_NAME_FOR_GOOGLE_ASSISTANT
      aliases:
        - BRIGHT_LIGHTS
        - ENTRY_LIGHTS
    light.living_room:
      expose: false
      room: LIVING_ROOM

OMG :confounded:

can not believe that this happened
