Most likely you can’t usу geocoding api.
In order to use address feature you need to enable the Geocoding Service.
Before using the Geocoding service in the Maps JavaScript API, first ensure that the Geocoding API is enabled in the Google Cloud Platform Console, in the same project you set up for the Maps JavaScript API.
