This is easily done with opus 4.6, uninstall the astro integration, then just npm/npx the pagefind https://github.com/Pagefind/pagefindpackage it's better if you are off all the integrations anyways- they come with a lot of overhead and deps, and you are relying on a single maintainer.

Thanks for raising the issue. I'll take a look at migration guide to see what's potentially breaking.
