Paragraphs in preview mode not working

Oh,
Hmmm, quick look at it and it would be the difference between our `EntityPreviewBuffer` to get the node, and the `EntityRevisionBuffer` used by the GraphQL module `entity_reference_revisions` data producer, to get the related entities.

This issue would have been introduced when we moved to a producer vs a looping entity loader via the $node->field_whater->entity. Mainly for cache and speed and less ownership over the code.

Issue would probably affect any unsaved entity reference in preview (eg via inline entity module)

Solution could probably get introduced in the gqlc `EntityReferenceRevisionsItem`
Maybe a new shimmed producer, or a switch into a another producer for previews, or do some dodgy old loading when in previews.

I reckon we can fix it.

This seems to be related.

Ok, lets give this a whirl.

In the route i'm setting a preview context
Then in the resolver I'm running a `cond` on that to use the property or the buffer.

Let me know how you go.

Code works as intented. Can be merged.

Thanks Almunnings!

Merged into 2.1.x-dev

It looks like the changes that happened in your merge request are removed from 2.1, in a later commit. I added a patch to re-include these changes, so the preview with paragraphs works again.

Afternoon brodeo,
Perhaps I wasn’t super clear in the other ticket. My bad.

I can’t reintroduce these changes, as they bypass access controls on referenced entities in preview mode.

The fix you’re looking for with anonymous/other user previews is in graphql_compose_preview dev module, which alters node access.

Unless you’re saying the previews don’t work for the same user?
