Catchable fatal error: Closure object cannot have properties

    I get this error:

    
Catchable fatal error: Closure object cannot have properties in /srv/www/my-site/htdocs/WP/wp-includes/post.php on line 522

    It traces back to wordpress_seo/admin/metabox/class_metabox.php:793:

    
if ( wp_is_post_revision( $post_id ) ) {
    $post_id = wp_is_post_revision( $post_id );
}

    The $post_id returns something that is not an ID:

    
Closure Object
(
    [parameter] => Array
        (
            [$attachment_id] => <required>
        )

)

    Any idea what might cause this? It happens on php 5 and php 7.1.

    Sometimes strange behavior may be caused by a plugin or theme conflict. The fastest way to rule out conflicts is to deactivate all non-Yoast plugins and switch to a standard theme like Twenty Seventeen. If this resolves the issue, you have a conflict and should activate one plugin at a time until you locate the conflict. Finally, after all plugins are active, switch to your theme. This will narrow down the conflict to a specific plugin or theme.

    If you are unfamiliar with checking for conflicts, we wrote a small guide that will walk you through the steps. You can find it here: How To Check For Plugin Conflicts

    It was caused by a weird combination of do_action('add_attachment') and a missing imageMagick library in the server. I added imageMagick and changed do_action to add_action and error went away.

    Thanks for your kind reply!
