@justinleet my bad. The search query to fetch all the alerts in a group was
returning a nested object since I was passing 'source: type' twice in the
fields. I don't know why I was getting a nested object if I pass the same
column name twice but for now, I fixed it in the UI.
The test spec for the above issue is in flight...---
