my folder structure

When i navigate here I get the 404 error
http://localhost:3000/dashboard/invoice/uuid/edit

route should be defined inside the app folder

I've been following this guide: https://nextjs.org/learn/dashboard-app/mutating-data

you create it inside the ui folder so the url should be /ui/invoices/uuid/edit

yes I got your point but it is how they have done in the above guide

oh i see

thanks @Ray .. the issue has been resolved now 😃

how do I mark it as answered?
