[ERROR] ! #355: Error occurred while handling event 'ServerEvents.recipes': TypeError: Cannot call method "forEach" of undefined (server_scripts:unify.js#355)

Only thing I can recommend is turning off recipe de-dupe, downgrading KubeJS, or looking into a newer replacement mod like Almost Unified (which has versions from 1.18.2+)

KubeJS keeps making breaking changes to nearly all their internals all the time, so it's nearly impossible for me to fix everything.
