Next.js 13 Dynamic Route: A required parameter (slug) was not provided as a string in generateStaticParams for /[lng]/blog/[slug]

问题

I'm working on a Next.js 13 project that requires internationalization support and a blog. Here is the structure of the app folder:

app
--[lang]
----blog
------page.tsx
------[slug]
--------page.tsx

The [lang] part is for links of different languages:
http://localhost/en/about
http://localhost/fr/about

The blog part is for the post list:
http://localhost/en/blog
(shows a list of all blogs)

The [slug] part is for the post detail:
http://localhost/en/blog/my-first-post

Before I add the [lang] part, everything works fine, but now, I got an error:
Error: A required parameter (slug) was not provided as a string in generateStaticParams for /[lng]/blog/[slug]

But in my page.tsx under [slug], there's no generateStaticParams:

type PageProps = {
  params: {
    slug: string
  }
}

export default function Post({ params: { slug } }: PageProps) {
...

Is the folder structure correct?

I believe this is caused by the two dynamic routes [lang]/blog/[slug], but don't know how to fix it. I tried to do it the old way (before Next.js 13):

app
--[lang]
----blog
------page.tsx
------[slug].tsx

But no luck, any idea?

(or should I get the params with useRouter and pass them the component with generateStaticParams?)
