Description

@flar

A PR was hung up on a failed "Dashboard check". When I reviewed the failure I ended up at a log that is marked as a failure, but none of its steps are indicated as a failure.

PR: #194200
Failed task log: https://ci.chromium.org/ui/p/flutter/builders/try/Windows%20Engine%20Drone/1029721/overview

    I think this might have been a post-us problem with LUCI:

    This looks like a LUCI-side failure to report the status of the build back to cocoon. This is pretty rare and there isn't much we can do about it on our side. Closing.
