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

Actually, it failed on the same platforms for the central-as-late-beta simulation.

Comment 2

[Nicolas Chevobbe [:nchevobbe]]

Tom, is the stacktrace retrieval for promise rejection behind a pref or something?
The failure screenshot seems to indicate we don't have them in Beta simulation: https://firefoxci.taskcluster-artifacts.net/cTPBJkRZR_ikSHRIoT-6Ag/0/public/test_info//mozilla-test-fail-screenshot_HHNYHf.png

Comment 3

[Tom S [:evilpie]]

Yes. It is actually! We need to set javascript.options.asyncstack like we did in bug 1638549.

Comment 4

[Nicolas Chevobbe [:nchevobbe]]

okay thanks! Let me do that

Comment 5

[Nicolas Chevobbe [:nchevobbe]]

Attachment: Bug 1639305 - Fix beta simulation failure in browser_webconsole_promise_rejected_object.js. r=evilpie.

The javascript.options.asyncstack pref is needed for unhandled
rejected promises messages to have a stacktrace.
