REST API call to get alarms with the Dynamic Alarm Title attribute (0x12b4c) fails with NullPointer exception

Issue/Introduction

Running the following REST alarms query is generating a NullPointerException and preventing alarms from going to splunk. 

https://ocserver/spectrum/restful/alarms?attr=0x1006e&attr=0x12d7f&attr=0x10000&attr=0x10009&attr=0x12b4c&attr=0x11f4e&attr=0x1321a&attr=0x11f9c&attr=0x11f56

Environment

DX NetOps Spectrum 23.3.6

Cause

This is occurring b/c the DynamicAlarmTitle attribute had a value of "N/A".  I believe that was breaking the XML response and causing the NULL Pointer Exception.

Resolution

Clearing the existing alarms with a value of "N/A" for the alarm title and adding a alarm title to the event in the Event Configuration Editor for the event missing an alarm title will resolve the issue.
