Comment 7

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Since it started again, it's frequent. https://hg.mozilla.org/integration/autoland/log?rev=inspector doesn't list any devtools commit close to it. Can you check the recent commits if anything looks related?

Comment 8

[Julian Descottes [:jdescottes]]

This is most likely from Bug 1655427. We removed calls to allowMatchingRejectionsGlobally that were performed in the middle of the test suite (see https://bugzilla.mozilla.org/show_bug.cgi?id=1655422 for why this can be bad, tldr can make tests pass in a suite but fail in isolation).

I tried fixing all the intermittents I found before landing it, but I'm not surprised some old intermittents come back.
If you see any other intermittent in devtools/client/inspector/test/ for A promise chain failed to handle a rejection: Error: Connection closed then it's also probably from the same bug.
