How to get Assist to close blinds in given area?

I’m trying to close blinds in a given area.

Home assistant is throwing an error saying it can’t find entities when trying to run this sentence based on cover_HassTurnOff:

“close Office blinds”

homeassistant.helpers.intent.IntentHandleError: No entities matched for: name=None, area=AreaEntry(name='Office', normalized_name='office', aliases=set(), id='office', picture=None), domains={'cover'}, device_classes={'blind'}

    result = await handler.async_handle(intent)
  File "/usr/src/homeassistant/homeassistant/helpers/intent.py", line 394, in async_handle
    raise IntentHandleError(

I’ve tried various renditions of changing casing but to no avail.

Blinds are indeed added to the “Office” area.
