if ( $is_image && $model->target_post_id ) {
        list( , $width, $height ) = \wp_get_attachment_image_src( $model->target_post_id, 'full' );

        $model->width  = $width;
        $model->height = $height;
        $model->size   = \filesize( \get_attached_file( $model->target_post_id ) );
    }

в этой строке проблема $model->size = \filesize( \get_attached_file( $model->target_post_id ) );
