Hi All. I'm upgrading a studio to v3 and it's all working apart from the production previews. In v2 I was using (resolveProductionUrl.js):
export default function resolveProductionUrl(document) {

if (document._type == "page"){
`return `
https://sitename.netlify.app/page-preview/${document._id} ``
}

if (document._type == "product"){
`return `
https://sitename.netlify.app/product-preview/${document._id} ``
}

if (document._type == "post"){
`return `
https://sitename.netlify.app/post-preview/${document._id} ``
}

}
But I'm struggling to get it working now. I find the migration docs difficult to understand in this area. Could anyone point me in the right direction? Thanks in advance!

Okay, to be more precise, in the migration docs it has this example:

document: {
    // prev is the result from previous plugins and can be composed
    productionUrl: async (prev, context) => {
      // context includes the client an other details
      const {client, dataset, document} = context

      if (document._type === 'post') {
        // you can now use async/await 🎉
        const slug = await client.fetch(
          `*[_type == 'routeInfo' && post._ref == $postId][0].slug.current`,
          {postId: document._id}
        )

        const params = new URLSearchParams()
        params.set('preview', 'true')
        params.set('dataset', dataset)

        return `<https://my-site.com/posts/${slug}?${params}>`
      }

      return prev
    },
  },
})
How can I modify this if I just want to query by document._id rather than slug?

Something like this should work:
document: {
    // prev is the result from previous plugins and can be composed
    productionUrl: async (prev, {document}) => {

      if (document._type == "page"){
    return `<https://sitename.netlify.app/page-preview/${document._id}>`
    }
    if (document._type == "product"){
      return `<https://sitename.netlify.app/product-preview/${document._id}>`
      }
    if (document._type == "post"){
        return `<https://sitename.netlify.app/post-preview/${document._id}>`
        }
  }

      return prev
    },
  },
})

Thanks so much for the reply. I can see you have a tidal wave of support queries to deal with! 🙏

This is all working now. I left out the:
 return prev
Fully upgraded to v3 now, thanks again for the support!
