Thanks for the issue. Could you provide more details about how and where you encountered the error, or possibly a code sample that reproduces it?

I will say that most commonly when I see the "Result for unknown rule" error it happens due to a JavaScript file that overrides native JS features, mainly things like JSON.stringify / parse or Array functions. You may try looking to see if the site loads any 3rd party scripts, for example http://prototypejs.org/, that would change native JS features.
