 To reproduce this create a CPT:

 {{{#!php
 <?php

         $labels = array(
                 'name'                  => _x( 'Post Types', 'Post Type

                 'description'           => __( 'Post Type Description',

                 'labels'                => $labels,
                 'supports'              => array( 'title', 'editor' ),
                 'taxonomies'            => array( 'category', 'post_tag'

                 'hierarchical'          => false,
                 'public'                => true,
                 'show_ui'               => true,
                 'show_in_menu'          => true,
                 'menu_position'         => 5,
                 'show_in_admin_bar'     => true,
                 'show_in_nav_menus'     => true,
                 'can_export'            => true,
                 'has_archive'           => true,
                 'exclude_from_search'   => false,
                 'publicly_queryable'    => false,
                 'capability_type'       => 'page',
                 'show_in_rest'          => true,
         );
         register_post_type( 'post_type', $args );

 }
 add_action( 'init', 'custom_post_type', 0 );
 }}}

 Then create an item and publish. After the item is saved, edit the title
 and wait until the autosave is triggered. The autosave fails without any
 JS error.

 Also if you make the CPT set "public" to false but "publicly_queryable" to
 true and create and publish an item after I refresh the editor I get the
 following JS error:
