Cause

There was a software issue in the 8.2.0-1.12 release. This was with the REST API Cyber Recovery uses to discover all the CyberSense interfaces.
It returns an invalid json response if one or more of the CyberSense interfaces is unconfigured or not enabled.
Cyber Recovery could not parse this response and the error seen in both the logs and the Cyber Recovery is displayed.

Resolution

This issue is addressed in CyberSense 8.2.0-1.23.
