"WARNING: Iceberg REST client is missing the OAuth2 server URI configuration and defaults to https://biglake.googleapis.com/iceberg/v1beta/restcatalogv1/oauth/tokens. This automatic fallback will be removed in a future Iceberg release.It is recommended to configure the OAuth2 endpoint using the 'oauth2-server-uri' property to be prepared. This warning will disappear if the OAuth2 endpoint is explicitly configured. See https://github.com/apache/iceberg/issues/10537"; -- This is an automated message from the Apache Git Service.
