😿 Pinpoint job stopped with an error.
https://pinpoint-dot-chromeperf.appspot.com/job/12243963240000

All of the runs failed. The most common error (20/20 runs) was:
Exception: Shard indicators must be present for perf tests

Emily, any idea what this error means? I'm trying to run a bisect on a regression that I think took place around 2 months ago. Wondering if it has anything to do with recent buildbot step refactorings or resharding.

Yes, it's related to the buildbot step refactorings:

There were some fixes on the Chromium side. It will be possible in the near future to re-run the job with those fixes applied, but it's not working right now:

Makes sense. I'll snooze this bug and stay posted.

Marking this as WontFix - this was mostly to appease my own curiosity anyhow.
