Nope that code produces same error.
Interestingly,
wp.data.select( 'core/editor' ).getEditedPostAttribute( 'featured_media' ) === undefined
Despite their being a featured_media item set.
Does anybody know how to change ANY value inside the edit post window?
I wanted to make progress so I’ve removed the plugin and hard-coded a menu.
Would love to hear if you know what the solution was, else please close the thread.
Thank you.
