plugin not working on my custom post type

Hi,

I am using wordpress version 4.9.1

Intially I used the postname as permalink for better SEO. But our site only available in arabic language so arabic postname is converted to ascii code and it becomes lengthier URL. So tried to avoid post name and changed tonplain url ?p=/%post_id/. But the custom posts still showing as postname with URL and installed your extension CPTP and selected /%post_id/ as permalink for the custom post carricatures

But not worked

In function.php

register_post_type( ‘caricatures’,
// CPT Options
array(
‘labels’ => array(
‘name’ => __( ‘Caricatures’ ),
‘singular_name’ => __( ‘Caricature’ )
),
‘public’ => true,
‘has_archive’ => true,
‘rewrite’ => [
‘with_front’ => true
],
‘cptp_permalink_structure’ => ‘%post_id%’,
‘rewrite’ => array(‘slug’ => ‘caricatures’),

)
);

What is the issue
