The error message is not showing on Login Observer if the error occours.

observer file is :


namespace Orbitx\Emailblock\Plugin;

use Magento\Framework\Controller\ResultFactory;
use Magento\Framework\UrlInterface;
use Magento\Framework\Controller\Result\RedirectFactory;
use Magento\Framework\UrlFactory;
use Magento\Framework\Message\ManagerInterface;
use Magento\Framework\App\Config\ScopeConfigInterface;
use Magento\Store\Model\ScopeInterface;

class RedirectCustomUrl
protected $resultFactory;
protected $url;
protected $_request;
protected $_response;
protected $urlModel;
protected $resultRedirectFactory;
protected $messageManager;
protected $scopeConfig;
protected $MessageManager;

public function __construct(
    \Magento\Framework\App\Action\Context $context,
    UrlInterface $url,
    UrlFactory $urlFactory,
    RedirectFactory $redirectFactory,
    \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
    ManagerInterface $messageManager,
    ResultFactory $resultFactory,
    \Magento\Framework\Message\ManagerInterface $MessageManager,
    \Magento\Framework\App\ResponseFactory $responseFactory

    $this->_request = $context->getRequest();
    $this->MessageManager = $MessageManager;
    $this->_response = $context->getResponse();
    $this->url = $url;
    $this->resultFactory = $resultFactory;
    $this->urlModel = $urlFactory->create();
    $this->resultRedirectFactory = $redirectFactory;
    $this->scopeConfig = $scopeConfig;
    $this->messageManager = $messageManager;
    $this->_responseFactory = $responseFactory;

public function aroundExecute(\Magento\Customer\Controller\Account\LoginPost $subject, \Closure $proceed) {    
    $email = $subject->getRequest()->getPost('login')['username'];
    if ($email == '[email protected]') {
            'Registration is disabled for you email'
        $defaultUrl = $this->urlModel->getUrl('*/*/login', ['_secure' => true]);
        /** @var \Magento\Framework\Controller\Result\Redirect $resultRedirect */
        $resultRedirect = $this->resultRedirectFactory->create();

        return $resultRedirect->setUrl($defaultUrl);

    return $proceed();

the exception 'Registration is disabled for you email' is not showing on frontend and if i entered wrong email or password it is also not giving any exception like 'your account is disabled'.

Can anyone tell me how to show the error message.

Any help is appriciated.

Create events.xml app/code/Vendor/Module/etc/events.xml

<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="customer_login">
        <observer name="customer_login_observer" instance="Vendor\Module\Observer\CustomerLoginTest" />

in your observer class app/code/Vendor/Module/Observer/CustomerLoginTest.php


namespace Vendor\Module\Observer;

use Magento\Framework\Event\ObserverInterface;

class CustomerLoginTest implements ObserverInterface
    public function execute(\Magento\Framework\Event\Observer $observer)
        echo "Customer LoggedIn";
        $customer = $observer->getEvent()->getCustomer();
        echo $customer->getEmail(); //Get customer name
        //add your custom code here//
  • Thanks for answer @nihal but i have got the email. Just the error message is not showing on front-end please read my question again.
