Symptoms

Show generic-objects API command fails with "Management Server failed to execute command" error message.

$MDS_FWDIR/log/cpm.elg file shows:

DATE TIME ERROR infrastructure.logging.DefaultExceptionLoggerHandlerImpl [qtp-634337094-14500]: 
incident [f68e6e73-55d3-4da8-a598-7a37740cf979]: 
java.lang.IllegalArgumentException: Expected single result for object with uid 
0ddadb74-3ccf-2e4c-96f8-2dc2962a46d9, got: 0 (through reference chain: com.checkpoint.objects.classes.dummy.CpmiVsClusterNetobj["domain"])

	at com.checkpoint.management.api.services.internal.ApiGenericObjectSvcImpl.getDleObjectAsJson(ApiGenericObjectSvcImpl.java:3)

Error can originate from 3rd party security orchestration solution (Tufin, Skybox, Algosec etc.) that uses the Management API.

Cause

Due to independence of revisions count of System Domain and User Domain, in case admin is logged-in to a specific revision (e.g. last-published-session), while fetching an object there might be miss match between Domains' revisions which will lead to failure of fetching requested information.
