Status: UNCONFIRMED

(Testing :: mozregression, defect, P3)

Description

[Kevin Locke]

Attachment: `mozregression --good 2022-05-24 --bad 2022-05-28 --mode no-first-check` output

Using mozregression 4.0.18 or git main (4cef6a8), sometimes entering "retry" in response to the prompt causes mozregression to fail with the following output:

 1:26.67 INFO: Running mozilla-central build built on 2022-05-26 11:11:10.206000, revision e7aef329

Saw this error a few times today. For me it seems to happen when retry is entered for a build that was adjusted by approx-policy
