VMWare Smart Assurance: Singleton error seen in Domain manager log file or running ASL file with sm_adapter

The following error is seen:

MR-NON_SINGLETON_SET-Set operation produced a set which is not a singleton

Environment

VMware Smart Assurance - SMARTS

Cause

The system is trying to access a attribute of a class where this attribute has a NULL value.

Resolution

To workaround this error, add ? IGNORE; to the end of the access call in ASL, or make sure that the value being accessed is not NULL.

Example
num = "";
num = hsrpEpObj->GroupNumber ? IGNORE;
