Failed to import File_name Invalid post type jp_pay_product

Although it will not fix the error, if your goal is to just remove it from view you could edit your wp_config file and above the stop editing line put the following:

ini_set('display_errors','Off');
ini_set('error_reporting', E_ALL );
define('WP_DEBUG', false);
define('WP_DEBUG_DISPLAY', false);

As far as whats happening from what I can guess there was a post type called jp_pay_product on the old site and the new one does not have it. A possible quick and dirty way to get rid of it would be to create that post type in your functions.php inside your themes directory. Run the import then remove the code.
Here is some code to do that:

function create_jp_pay_product_post_type() {
    register_post_type('jp_pay_product', array(
        'labels' => array(
            'name' => __('JP Pay Products'),
            'singular_name' => __('JP Pay Product'),
        ),
        'public' => true,
        'supports' => array('title', 'editor', 'thumbnail'),
    ));
}
add_action('init', 'create_jp_pay_product_post_type');
