[Erich Gubler [:ErichDonGubler]]

I've been able to work around this locally by running an older version of Python, i.e., python3.10 mach test …. Does that work for you, :jrmuizel?

:jgraham, could you have a look please?

I have the same problem. It fails with my current python version (3.13), but works with

python3.12 ./mach test testing/web-platform/tests/clear-site-data/set-cookie-after-clear-all.https.html

Also adding mach-busted, because I would have found this bug report earlier, if it would have been in there. And seems to be fitting due to python 3.13 being released already.
