Good morning. I'm a bit confused about how to correctly "force" NotFound to render in my case (or in general). After all, we have /: user - the user's url will always match and "interfere" with NotFound, in which direction to dig or maybe give an example? You are welcome)

Answer 1

Can be handled in an asynchronous activity or in a user component. If the server returned a 404 instead of a user and a message like 'ApiObjectNotFound', redirect to the NotFound page.
Don't forget to make a list of reserved words that can't be used for the user's slug.
