image-select error

The metabox looks like this:

?php

add_filter( 'rwmb_meta_boxes', 'your_prefix_register_meta_boxes' );

function your_prefix_register_meta_boxes( $meta_boxes ) {
    $prefix = '';

    $meta_boxes[] = [
        'title'      => esc_html__( 'drk-content', 'text-domain' ),
        'id'         => 'drk-content',
        'post_types' => ['post'],
        'context'    => 'side',
        'priority'   => 'high',
        'fields'     => [
            [
                'id'       => $prefix . 'thumb-image',
                'type'     => 'image_select',
                'name'     => esc_html__( 'Thumb Image', 'text-domain' ),
                'desc'     => esc_html__( 'Thumb image for grid feature', 'text-domain' ),
                'required' => 1,
            ],
        ],
    ];

    return $meta_boxes;
}
