The APM to SAM integration is not happening.
The Event service throws this error: Error in deserializing body of reply message for operation 'get_data_sources'. System.InvalidOperationException: There is an error in XML document (1, 660). ---> System.InvalidCastException: Cannot assign object of type System.Int32 to an object of type System.String.
This issue has been fixed in CA Asset Portfolio Management 14.1, C3 + T57T072 and above.
If you are using CA Software Asset Manager 3.6.5 or lower, then also upgrade to the latest CA SAM 4.1 release.
