Answer 1

The error indicates that the Vora Catalog is either not installed or not running correctly.
Since the Vora Catalog relies on the Vora DLog, the DLog also needs to be installed and running. For install instructions see Vora Installation and Administration Guide.
You can check the Vora Discovery Server UI (:8500/ui) for a 'green' entry for 'vora-catalog' and 'dlog'. In case of issues, you can check the log files /var/log/vora-catalog and /var/log/vora-dlog.
