No default component was found

Description

Hello,

I followed https://github.com/amannn/next-intl/tree/main/examples/example-app-router exemple to install next-intl. When I reach a wrong url, like 'https://next-intl-example-app-router.vercel.app/sdsdsd' i'm well redirected to 404 custom page. Well, but i can see a warning in the browser console (see the screenshot below) talking about default.js component :

it's talking about Parallel Routes but like i said i only reproduced the structure based on the example source code :

This warning doesn't appear with 'yarn start' only with 'yarn dev' command.

Must i take care about this warning or it's normal ? i don't understand it

It looks like a false warning to me from Next.js, as there are clearly no parallel routes used in the example. If you'd like to help, you could report this on the Next.js repo!
