Bulk delete of OI alarms is returning an error 500 on All Alarms page,
Release : SAAS
Component : CA DOI ALARM ANALYTICS
Issue did not reoccur. No har file generated.
OI can show closed alarms toggle in the all alarms page and see the closed timestamp, one can check if there are any alarms closed during that time. This might not be the exact root cause, but this might be one of the possible scenarios.
When the issue happens next time, please try to capture har file. Engineering can get the alarmIds from har file which failed to close, based on that, can debug further.
