Notice: map_meta_cap was called incorrectly

by

I created an external script to import json data into a custom post type that uses wp-load.php. Everything works fine but after every update I get the message 

Notice: map_meta_cap was called incorrectly. The post type EXAMPLE is not registered, so it may not be reliable to check the capability "edit_post" against a post of that type.

Im calling the script inside a child theme and post_type_exists returns false but works fine…

Ive seen a similar notice in a core track thread but it talks about comments being the issue and my post type doesnt have any comment functionality.

function child_post_types() {

$labels = array(
    'name'                => _x( 'Courses', 'Post Type General Name', 'test' ),
    'singular_name'       => _x( 'Course', 'Post Type Singular Name', 'test' ),
    'menu_name'           => __( 'Courses', 'test' ),
    'parent_item_colon'   => __( 'Parent Course:', 'test' ),
    'all_items'           => __( 'All Courses', 'test' ),
    'view_item'           => __( 'View Course', 'test' ),
    'add_new_item'        => __( 'Add New Course', 'test' ),
    'add_new'             => __( 'Add New', 'test' ),
    'edit_item'           => __( 'Edit Course', 'test' ),
    'update_item'         => __( 'Update Course', 'test' ),
    'search_items'        => __( 'Search Courses', 'test' ),
    'not_found'           => __( 'Not found', 'test' ),
    'not_found_in_trash'  => __( 'Not found in Trash', 'test' ),
);
$args = array(
    'label'               => __( 'Course', 'test' ),
    'description'         => __( 'Courses', 'test' ),
    'labels'              => $labels,
    'supports'            => array( 'title', 'thumbnail', 'editor', 'revisions', 'author' ), //editor, thumbnail, title, author, excerpt, trackpacks, custom-fields, comments, revisions, page-attributes, post-formats 
    'hierarchical'        => false,
    'public'              => true,
    'show_ui'             => true,
    'show_in_menu'        => true,
    'show_in_nav_menus'   => true,
    'show_in_admin_bar'   => true,
    'menu_position'       => 5,
    'can_export'          => true,
    'has_archive'         => true,
    'exclude_from_search' => false,
    'publicly_queryable'  => true,
    'rewrite'             =>array('slug'=>'courses'),
    'capability_type'     => 'page',
);
register_post_type( 'course', $args );

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

And the script is sitting in my child theme just getting a local json file and looping through courses with wp_update_post()

require('../../../wp-load.php');

$data = json_decode( file_get_contents( 'wp-content/themes/_theme/courses.json' ), true );

foreach($data as $key => $c){

  $course = wp_update_post( array(
                'ID'    => $courseID, 
                'post_title' => $c['CourseTitle'],
                'post_content' => $c['Description'],
            ), true );
}

Any ideas?

Today i got exactly the same behaviour when adding a custom post type. I also noticed some admin post search tools stopped working. My debug_log showed exactly the same notice.

The problem turned out to be some text before the <?php opening tag (top file) were I register the CPT.

Example

some text here<?php
/**
 * @class My_Cpt_Class
 */
.......

The CPT does get registered correctly. I can add posts etc. But a few default post actions (from other plugins aswell) stop working for ALL post types. I have no idea why this happens with this error.
