'never' is no longer a valid mode when starting the connector

[fishwdev]

https://docs.synchdb.com/1.3/tutorial/sqlserver_cdc_to_postgresql/#cdc-only

SELECT synchdb_start_engine_bgw('sqlserverconn', 'never');

Connector configuration is not valid. The 'snapshot.mode' value is invalid: Value must be one of always, initial_only, configuration_based, when_needed, initial, custom, schema_only, no_data, recovery

Which snapshot mode can be used for CDC only now? Thanks.
