Description

Steps to Replicate:
1. Create a meta-alert.
2. Escalate the meta-alert.
3. Submit another search that filters the results to only show meta-alerts.
4. Sort the results by “alert_status” field.
5. The search will not return any meta-alerts in the results.
6. The REST log will contain the exception shown above.
