Google Assistant integration for Home Assistant Cloud

Hi, every one!! I have a problem with Google Assistant integration for Home Assistant Cloud, I configurated it and expose my scripts in order to do action with my ligths devices. But I can see an error in sync process.

The error when I clic in PRESS button is > Failed to call service button/press. Unable to sync devices with result code: 404, check log for more info.

Error Log:
