Rely merchandise with customized metadata subject in an order

I’ve a wordpress plugin which performs a depend of bought merchandise in an order that are flagged with my customized metadata worth.
The customized metadata worth is within the type of a checkbox throughout the product web page. I am utilizing WooCommerce/WooCommerce subscriptions.

If a buyer purchases 5 merchandise, a depend is completed after which saved in a variable. Solely merchandise which have the customized metadata worth checkbox are counted.

The depend doesn’t happen, as I imagine my customized metadata worth checkbox shouldn’t be being detected when utilizing get_meta(); throughout the loop.

Code beneath exhibits the metadata checkbox

/* Including Further subject to product to Allow Traccar integration */

// Show Fields
add_action('woocommerce_product_options_general_product_data', 'wootraccar_product_custom_fields_add');
perform wootraccar_product_custom_fields_add(){
    international $publish;

    echo '<div class="wootraccar_product_custom_field">';

    // Customized Product Checkbox Area
    woocommerce_wp_checkbox( array(
        'id'        => '_wootraccar_integration',
        'desc'      => __('Verify this field if Traccar integration is required for this product', 'woocommerce'),
        'label'     => __('Traccar Integration Required', 'woocommerce'),
        'desc_tip'  => 'true'
    ));

    echo '</div>';
}

// Save Fields
add_action('woocommerce_process_product_meta', 'wootraccar_product_custom_fields_save');
perform wootraccar_product_custom_fields_save($post_id){
    // Customized Product Textual content Area
    $wootraccar_integration = isset( $_POST['_wootraccar_integration'] ) ? 'sure' : 'no';
        update_post_meta($post_id, '_wootraccar_integration', esc_attr( $wootraccar_integration ));
}

the for every loop

        $order = wc_get_order( $order_id );
        $electronic mail  = $order->get_billing_email();
        $identify = $order->get_billing_first_name();

        $devicecount =0;

            foreach ( $order->get_items() as $merchandise ) {
            if( $item->get_meta( '_wootraccar_integration', true )=='sure')
            {
                $devicecount = $devicecount +  $item->get_quantity();
            }
        }
