I am using Magento 2.1.3 and I need to display an error message in the shipping information page. Currently I'm using this code:

throw new StateException(__('Shipping is not available on the provided zipcode'));

but the issue is that the error message is just showing 2 or 3 seconds. I need to show this message up to refresh the page.

<?php

namespace SemShipmentPluginCheckoutModel;
use MagentoFrameworkExceptionStateException;
use MagentoCheckoutModelSession;
use MagentoFrameworkViewElementMessages;
use MagentoFrameworkMessageManagerInterface;
use MagentoFrameworkUrlInterface $urlInterface;

class ShippingInformationManagement


 protected $_messageManager;
 protected $jsonResultFactory;
 protected $_checkout; 

 public function __construct(
 MagentoFrameworkAppActionContext $context,
 MagentoFrameworkControllerResultJsonFactory $jsonResultFactory,
 MagentoFrameworkMessageManagerInterface $messageManager,
 MagentoFrameworkControllerResultJsonFactory $resultJsonFactory,
 MagentoCheckoutModelSession $session,
 MagentoFrameworkUrlInterface $urlInterface

 ) 
 $this->_messageManager = $messageManager;
 $this->jsonResultFactory = $jsonResultFactory;
 $this->_session = $session;
 $this->_urlInterface = $urlInterface;
 

 public function beforeSaveAddressInformation(
 MagentoCheckoutModelShippingInformationManagement $subject,
 $cartId,
 MagentoCheckoutApiDataShippingInformationInterface $addressInformation

 )
 
 $objectManager = MagentoFrameworkAppObjectManager::getInstance();
 $resource = $objectManager->get('MagentoFrameworkAppResourceConnection');
 $connection = $resource->getConnection();
 $items = $this->_session->getQuote()->getAllVisibleItems();
 $address = $addressInformation->getShippingAddress();
 $postcode = $address->getData('postcode');
 $result = $this->jsonResultFactory->create();
 $pid='';
 if (count($items) > 0)
 foreach ($items as $item)
 
 $pname= $item->getName();
 $pid=$item['product_id'];
 $carttotal=$item['grand_total'];
 $weight=$item['weight'];
 $sql ="SELECT ca.postcode FROM
 mgcb_marketplace_product mp
 JOIN mgcb_marketplace_userdata mu ON mp.seller_id = mu.seller_id
 JOIN mgcb_customer_entity ce ON mu.seller_id = ce.entity_id
 JOIN mgcb_customer_address_entity ca ON ce.entity_id = ca.parent_id
 WHERE(mp.mageproduct_id = '$pid')";
 $qryresult = $connection->fetchAll($sql);
 foreach ($qryresult as $qryresult)
 
 $pikup=$qryresult['postcode'];
 

 foreach($result as $object) 
 $stat = "NO SERVICE AVAILABLE";
 
 //print_r($object);
 if($stat=="NO SERVICE AVAILABLE")
 

 $msg = "Shipping is not available on the provided zipcode For the following product: <em>" . $item->getName() . "</em>
 Currently Added Product : " . $linkUrl;
 $this->_messageManager->addError(__("errorr"));
 throw new StateException(__($msg));
 

 
 
 

I know it's three months down the line, but am sure this will help someone.

You can do this by adjusting the timeout period on the file.

vendor/magento/module-ui/view/frontend/web/js/view/messages.js

It is around lines 70/71. you can set the time out to be a figure of your choice (in milliseconds)
