Error reading Safari cookies on Big Sur

[ericmigi]

Attempting to run the example safari script https://github.com/zellyn/kooky#safari on Big Sur.

Getting this error:

2020/11/19 11:46:05 open /Users/eric/Library/Cookies/Cookies.binarycookies: operation not permitted

Even as sudo doesn't work, also tried granting the binary full disk access in settings, no luck.

Has anyone been able to get this to work? Chrome works fine on Big Sur

Have you tried restarting the executing app after giving full disk access to them? I had to give full disk access to my terminal application.
