Overview

The Manage Dependencies page does not display any dependencies, even though the Group By column indicates that dependencies exist.

When you check the OrionWeb.log file, the log displays the following errors:

ERROR SolarWinds.Orion.Core.Common.SwisEntityHelper - (null)  
Unknown entity 'UNKNOWN'
ERROR DependenciesTree - (null)  Exception in BuildTree: System.Exception: 
Unknown entity 'UNKNOWN'
