Hi, I need help with Iframe preview, I have a 
route
schema with unique 
slug
(
/lb/123
) and also I have 
page
schema with the content for that route now the problem is how do I add the 
slug
property to the 
page
schema so the preview can work ? been stuck on this from hours 😪

So you want to get the 
route
that a page is connected to, and show the preview for that route, right?

Exactly, I have the page referenced in the route schema.
{
      name: 'page',
      type: 'reference',
      validation: (Rule) => Rule.required(),
      description: 'The page you want to appear at this path. Remember it needs to be published.',
      to: [
        {
          type: 'page'
        }
      ]
    },
I just need to access the 
slug
for this route on the connected page!

Check if something like this work:
 S.documentList()
              .title('Active pages')
              .id('pages')
              .schemaType('page')
              .menuItems(S.documentTypeList('page').getMenuItems())
              .filter('_type == "page" && _id in *[_type == "route"].page._ref')
              .child(async documentId => {
                const slug = await client.fetch(
                  `*[_type == "route" && page._ref == $documentId][0].slug.current`,
                  { documentId }
                )
                return S.document()
                  .documentId(documentId)
                  .schemaType('page')
                  .views([
                    S.view.form(),
                    S.view.component(PagePreview).title('preview'.options({ slug })
                  ])
              })
          ),

in the top of the file

you can of course do this datafetching in the preview component too, might even be better actually

Thank you, I'm getting 
id
is required for view item error
Dec 21, 2020, 8:50 PM

.title('Preview')
 to the component
Dec 21, 2020, 8:50 PM
