I just installed prismic on my nextjs project everything works fine if i launch it with `pnpm run dev` . but it fails if i try to build it for production:

```auto

  response: undefined
}

```

when i go to that url, it returns:  
`{"page":1,"results_per_page":1,"results_size":0,"total_results_size":0,"total_pages":0,"next_page":null,"prev_page":null,"results":[],"version":"877bfdc","license":"All Rights Reserved"}`

Here how i fetch it:

```auto
export async function generateMetadata(): Promise<Metadata> {
  const client = createClient();

  const metadata = await client.getSingle("metadata");

  return {
    title: metadata.data.title,
    description: metadata.data.description,
  };
}

```

I have published 'metadata'.

And yes it's single type.

the most weird things is why it works in dev but fails in prod

Hi @dandraghas ,

Welcome to the community 🙂

Since your project is failing in prod (maybe vercel?) it's most likely the ongoing Next.js cache issue.

> Dear Prismic team I set up a new Next.js App Router project using your setup command npx @slicemachine/init@latest and walking trough your step by step setup guide. In previous versions, I never had issues deploying the site to Vercel and setting up Prismic Webhooks to trigger redeploys. With this new project it seems like there are some caching issues with Vercel: If I push a new commit to Github or if I edit content on Prismic, it triggers a new deploy correctly. Unfortunately those deplo…

Thanks.
