I am facing issue adding product in wishlist (magento version 2.2.3).

Here is scenario,

Step 1 :- Make sure customer not logged in.

Step 2 :- Go to product list page and click "Add to wishlist"

Step 3 :- it will redirected to login page.

Step 4 :- Now after login you can check product not added in wishlist.

Generate new FormKey and replace for oldRequestParams Wishlist

1. 
   vendormagentomodule-wishlistHelperData.php
   
   just added below code in this file...

use MagentoFrameworkAppObjectManager;

use MagentoFrameworkDataFormFormKey;

use MagentoFrameworkAppPageCacheFormKey as PageCacheFormKey;

use MagentoFrameworkSessionConfigConfigInterface;

use MagentoFrameworkStdlibCookieCookieMetadataFactory;

 public function refreshFormKey()
 
 $beforeWishlistRequest = $this->_customerSession->getBeforeWishlistRequest();


 if ($beforeWishlistRequest !== null) 

 $formKeyData = ObjectManager::getInstance()->get(FormKey::class);

 //form_key is already empty
 $formKey = $formKeyData->getFormKey();

 $sessionConfig = ObjectManager::getInstance()->get(ConfigInterface::class);
 $cookieMetadata = ObjectManager::getInstance()->get(CookieMetadataFactory::class)->createPublicCookieMetadata();
 $cookieMetadata->setDomain($sessionConfig->getCookieDomain());
 $cookieMetadata->setPath($sessionConfig->getCookiePath());
 $cookieMetadata->setDuration($sessionConfig->getCookieLifetime());

 ObjectManager::getInstance()->get(PageCacheFormKey::class)->set(
 $formKey,
 $cookieMetadata
 );

 $beforeWishlistRequest['form_key'] = $formKey;
 $this->_customerSession->setBeforeWishlistRequest($beforeWishlistRequest);
 $this->_customerSession->setBeforeRequestParams($beforeWishlistRequest);
 $this->_customerSession->setBeforeModuleName('wishlist');
 $this->_customerSession->setBeforeControllerName('index');
 $this->_customerSession->setBeforeAction('add');
 

 return $this;

2. vendormagentomodule-wishlistObserverCustomerLogin.php

public function execute(Observer $observer)
 
 $this->wishlistData->refreshFormKey(); // add this line only
 $this->wishlistData->calculate();
