INVALID_SESSION_PROPERTY

INVALID_SESSION_PROPERTY

Error message

Unknown session property: %s.%s

What it means

FullConnectorSession.getProperty was asked for a catalog session property but the connector session has no property map (null properties), meaning the property name is unknown to this connector; rejected with INVALID_SESSION_PROPERTY. The catalog and property name are included.

Solutions

1. Check the property name spelling and that it belongs to the named catalog
