It looks like the Catalina Perf is failing due to unexpected output Running 206 tests Running Animation/balls.html (1 of 206) error: Animation/balls.html 2021-03-08 17:09:25.226 com.apple.WebKit.WebContent.Development[63077:5238896] -[NSURL init] called; this results in an NSURL instance with an empty URL string.

This did not occur on a run with https://trac.webkit.org/changeset/274100/webkit. but it did with https://trac.webkit.org/changeset/274117/webkit It appears related to REGRESSION (r273541): Payloads requiring NSURL in serialization fail https://bugs.webkit.org/show_bug.cgi?id=222856 https://trac.webkit.org/changeset/274109/webkit
FWIW this output is showing up in stderr for some layout tests, too: https://build.webkit.org/results/Apple-BigSur-Release-WK2-Tests/r274168%20(842)/results.html
