Has anyone got any insight on this message? Meltano 2.19.0

WARNING Unknown message type ACTIVATE_VERSION in message {'type': 'ACTIVATE_VERSION', 'stream': 'xxxxx-country', 'version': 1685617635386}

see https://hub.meltano.com/singer/docs/#activate-version i believe it is caused by the fact that while your tap supports and is using this functionality, your target does not. depending on your needs, this may be totally fine. e.g. i do incremental sync from postgres to bigquery, and don’t expect or require support for hard deletes, so i see this warning and just ignore it.

Thank you @luke_rodgers
