On NextJS (deployed in Vercel), by default, the 404 error page is .com/404. I need to change it to .com/errors/404.
I've tried reading the docs (https://vercel.com/guides/custom-404-page) and even asking to ChatGPT o3-mini-high, and there is no answer at all.
My problem is that my app/website show user-pages on .com/xxx, and the app got viral sooner than expected (getnofilter.com), and somebody registered the "404" username, so now .com/404 should show the user instead of the error page. Like .com/brodanoel (.com/[username]).
I'm using NextJS 14, and with the old folder routing (/pages/[username]/index.js)
Thanks in advance!
PD.: Yes, I already registered the error user, so I don't have a problem with .com/error/404 hahaha
