Alexandra, could this failure be from wptsync?
I did some backfills here .

Flags: needinfo?(aborovova)

I don't think it's directly wptsync, I don't see any changes in the test or metadata. It might be that wptsync update added some tests which moved this test to a different chunk and this uncovered some side effects. But in this case, I wouldn't just update metadata. Looks like general expectation is that this test should be passing.

Valentin, could you have a look?

This seems to be the same as bug 1919651 which has been failing with this error for many months now.
I think it's become a rough permafail in the past 3 months? see bug 1919651 comment 38.

The error is coming from erase_cookie_from_js called from partitioned-cookies.tentative.https.html
I assume the problem is that we have both a partitioned and unpartitioned cookie with the same name, and we only delete one of them?

Note the problem only happens under nofis runs - I haven't been able to repro locally.
I think this may have started / message might have changed in bug 1980997.

Andrea, you have any ideas why clearing the cookie would fail?

I don't have a good answer. I know that when we run WPTs, sometimes we see funny failures related to cookies left by previous tests. This was a serious issue for CookieStore WPTs. I wonder if the problem is in how we run WPTs in general. Maybe we should reset the profile more often, because this seems to be a mozilla specific bug.

Flags: needinfo?(amarchesini)
