We have released a new authentication mechanism for the connector. You need to provide Cloud Functions Invoker role to the service account email that is displayed in the connector setup form. You no longer need to grant the allUsers permission for your Google Cloud Function.
We are deprecating the old authentication mechanism that needed Google Cloud Storage (GCS) bucket configuration. Existing customers using GCS bucket configuration for authentication will be notified to migrate and use the new authentication mechanism.
We will continue to support the old authentication mechanism for existing customers for the next two months, so be sure to transition to the new authentication mechanism by July 15, 2020.
