    A recent code change introduced a bug resulting in some syncs failing with the message "T.cast: Expected type T::Struct, got type TrueClass". This impacted sync runs where there were no incremental changes identified and the source connection utilizes the Advanced Sync Engine. We identified the problematic change, and have reverted. Syncs are now running successfully.
