So I noticed that there was something wrong in the generateStaticParams function. when geting the sulg name, the fields was not exist.

// Return a list of `params` to populate the [slug] dynamic segment
export async function generateStaticParams() {
  const database = await getDatabase();
  return database?.map((page) => {
    const slug = page.properties.Slug?.**formula**?.string; // field error
    return ({ id: page.id, slug });
  });
}

I don't know the reason, may notion have upgrade the database definition. so I replaced it with this sentense:

const slug = page.properties.Slug?.rich_text[0].plain_text;

It seems worked.
