NuxtJS Article route wrong

Hi,

I followed this tutorial using NuxtJS: https://www.storyblok.com/tp/show-blog-content-in-nuxt

localhost shows me the current article, I can click on the article but it does not show the correct article.
It goes to following route: localhost:3000/articles/my-article and shows me this message:

This page could not be found

Back to the home page

I can access the page using this route.

localhost:3000/my-article

But I would like to access the article using this route like the blog article tells me to:

localhost:3000/articles/my-article

I checked my code against the given github repo aswell and I see no difference.
What could cause this from storyblok.
