Preview doesn't work for Advanded Custom Fields

[tobiasandersen]

I'm not sure if this is a bug report or a feature request — but I'm trying to get preview data for a page with ACF content, but I'm only able to retrieve non-ACF data. Given this query:

page(id: $id, idType: $idType) {
  preview {
    node {
      pageTemplate {
        template {
          ... on Page_Pagetemplate_Template_Hero {
            headline
          }
        }
      }
      title
      isPreview
      modified
    }
  }
}

The three bottom fields (title, isPreview and modified) all give me the expected preview data — but any data inside pageTemplate (set up in ACF) is stale. So in this case the headline property will never show the preview data.

For reference, I'm using Wordpress 5.6 and the following plugins:

• WPGraphQL for Advanced Custom Fields (0.4.0)
• WP GraphQL (1.1.1)
• Advanced Custom Fields PRO (5.9.3)

@tobiasandersen are you using Gutenberg or Classic Editor?

Classic!

I'm not familiar with asPreview, but sounds like this could be the same issue as described in #190?

[tobiasandersen]

The fix posted in #159 by @peteluffman seems to solve the issues I'm having as well.

@tobiasandersen I opened a PR which I believe might address this. Can you check #205 and let me know?

[tobiasandersen]

Thanks @jasonbahl! Short answer: it didn't fix my issue, but also commented in the PR.

@tobiasandersen I think the problem here is the use of the preview field instead of using asPreview. Try this:

page(id: $id, idType: $idType, asPreview: true) {
      pageTemplate {
        template {
          ... on Page_Pagetemplate_Template_Hero {
            headline
          }
        }
      }
      title
      isPreview
      modified
}

@jasonbahl maybe the preview field should be deprecated?

Oh, nvm my bad, I see it's working for me on both:
