      Fixed an issue where Central would panic and terminate Sensor connections, when a Sensor sent an event type unknown to Central.

      This occurred specifically when a Sensor version 4.9 was paired with Central version 4.7 or 4.8 on a cluster using OpenShift Virtualization.

      This fix ensures Central operates normally under these conditions and has also been applied to Central 4.9 to improve future compatibility with Sensors.

      USER PROBLEM
      What is the user experiencing as a result of the bug? Include steps to reproduce.

      • When Central receives an unknown grpc message from Sensor, the function `event.GetEventTypeWithoutPrefix` is called with nil argument and panics.

      CONDITIONS
      What conditions need to exist for a user to be affected? Is it everyone? Is it only those with a specific integration? Is it specific to someone with particular database content? etc.

      • for example: Sensor version being ahead of Central and sending a message that is unknown to Central

      ROOT CAUSE

      FIX
      How was the bug fixed (this is more important if a workaround was implemented rather than an actual fix)?
