How to run WebKit via the bisect-builds script? - macos

Question

WebKit has a script that is supposed to help bisect regressions as mentioned in this webkit blog post
I'm trying it out with
./bisect-builds -p mac-mojave -a x86_64 -c release -s 230000 -e 242118
and it downloads a release and runs the release but I can not navigate to any webpages regardless of which release it downloads. I can click a bookmark but typing a URL never works. I can not edit bookmarks (picking edit bookmarks does nothing)
When running I see the errors below in the terminal. That makes me wonder if I need to set some environment variables or something to tell webkit to not use ~/Library/Caches/com.apple.Safari and similar library folders but instead use some temp folder for all it's files since otherwise it would seem like they'd conflict with the system version of Safari.
This page on running webkit mentions nothing
I don't know those errors are the cause of not being able to navigate to pages but whatever the reason, so far it's been impossible to bisect if I can't load a test webpage.
How I can run the webkit bisect-builds script in a way that actually lets me test each webkit revision it launches?
