Hi,
I am trying to create a custom route to fetch an article based on its slug (defined as UUID). I am having a hard time following the tutorial here:

I created a fetch-slug.ts in the folders controllers, routes and services and I can’t even get the value of the parameters slug.
Here are my files:

//controller/fetch-slug.ts
export default {
  async fetchSlug(ctx) {
    try {
      const data = ctx.req.params.slug;
      ctx.body = {
        data,
      };
    } catch (err) {
      ctx.body = {
        error: "An error occurred while fetching article from slug",
        details: err instanceof Error ? err.message : "Unknown error",
      };
      ctx.status = 500; // Set the HTTP status code to 500 to indicate a server error
    }
  },
};

//routes/fetch-slug.ts
export default {
  routes: [
    {
      method: "GET",
      path: "/fetch-slug/:slug",
      handler: "fetch-slug.fetchSlug",
      config: {
        policies: [],
        middlewares: [],
      },
    },
  ],
};

Can somebody shed a light on how to read a parameter from a url (whether from the query or from req.params) and how to find an article from its slug?
Thanks all.

PS: I am currently using the endpoint:
/articles?filters[slug][$eq]=${slug}&populate=*
But as it doesn’t seem to work for localised versions for an article.
