bug: not adding editLink breaks DocFooter

[KalaayPT]

Vitepress version: 1.2.2
this bug is a bit convoluted to explain but bear with me:
i recently installed all of this and added the default config and whatever (i.e. used the plugin as intended). something i noticed almost immediately is that my site navigation (specifically, DocFooter prev and next page links, but also "Updated" text if a change hasn't been committed yet) is broken, see example:

what you can see here is that if i start on welcome, click next to go to "getting started" and land on the getting started page, i encounter three issues at once:

1. i do not have a "previous page" button
2. my "next page" button redirects to the page i'm on
3. LastUpdate says 54 years ago (i have not committed this page yet)

what absolutely baffled me when fiddling around with and trying to fix this myself is that all of this gets fixed instantly once i add editLink: { pattern: 'https://github.com/KalaayPT/Profit-Taker-Guide/edit/master/docs/:path' }, to my config.mjs in docs
