I have tried many solutions to fix this core issue. Whenever I am going to edit the order, update shipping or payment method and click on save. I am getting below error

Fatal error: Uncaught Error: Call to a member function getIsMultiShipping() on null in /var/www/html/project/vendor/magento/module-customer-balance/Observer/PaymentDataImportObserver.php:52 Stack trace: #0 /var/www/html/project/vendor/magento/framework/Event/Invoker/InvokerDefault.php(73): Magento\CustomerBalance\Observer\PaymentDataImportObserver->execute(Object(Magento\Framework\Event\Observer)) #1 /var/www/html/project/vendor/magento/framework/Event/Invoker/InvokerDefault.php(61): Magento\Framework\Event\Invoker\InvokerDefault->_callObserverMethod(Object(Magento\CustomerBalance\Observer\PaymentDataImportObserver), Object(Magento\Framework\Event\Observer)) #2 /var/www/html/project/vendor/magento/module-staging/Model/Event/Manager.php(97): Magento\Framework\Event\Invoker\InvokerDefault->dispatch(Array, Object(Magento\Framework\Event\Observer)) #3 /var/www/html/project/var/generation/Magento/Staging/Model/Event/Manager/Proxy.php(95): Magento\Staging\Model\Event\Manager->dispatch('sales_quote_pay...', Array) #4 /var/www/ht in /var/www/html/project/vendor/magento/module-customer-balance/Observer/PaymentDataImportObserver.php on line 52

I have debugged and came to know that Quote not generated properly. Due to that, I am getting this error. Please let us know if anyone has its solution to fix this issue.

  • If you are running EE there is pro support for you – Anthony Nov 27 '18 at 8:50
  • Yes, already created a ticket in the support, they are looking into it since 8days. – Nits Nov 27 '18 at 8:51
  • Could need alot of looking into. One option is to put it up on freelancer as a one time fix job. Should not cost much – Anthony Nov 27 '18 at 8:57
  • Thanks I don't have that option. – Nits Nov 27 '18 at 8:59

We got the solution for the above issue. In this issue, store not set up properly when we edit and save the order from the backend. So what I did, I have set an admin store when we edit and save the order. Please review the below code:


<type name="Magento\Framework\App\FrontControllerInterface">
        <plugin name="md_default_store_setter" type="Extension\Override\Plugin\DefaultStore" />


namespace Module\Override\Plugin;

 * Plugin to set default store for admin area.
class DefaultStore
     * @var \Magento\Store\Model\StoreManagerInterface
    protected $storeManager;

     * Initialize dependencies.
     * @param \Magento\Store\Model\StoreManagerInterface $storeManager
    public function __construct(
        \Magento\Store\Model\StoreManagerInterface $storeManager
    ) {
        $this->storeManager = $storeManager;

     * Set current store for admin area
     * @param \Magento\Framework\App\FrontController $subject
     * @param \Magento\Framework\App\RequestInterface $request
     * @return void
     * @SuppressWarnings(PHPMD.UnusedFormalParameter)
    public function beforeDispatch(
        \Magento\Framework\App\FrontControllerInterface $subject , \Magento\Framework\App\RequestInterface $request
    ) {

        $path =  $request->getParams();
        if(!empty($path) && isset($path['namespace']) && $path['namespace']=='product_listing'){
            //Fixed default store issue in the product grid backend(previously showing default store value instead of admin store).

Please run below commands

php bin/magento cache:flush or rm -rf var/*

If production mode is enable then you should run compilation command

php bin/magento setup:di:compile

and if require run static-content command

php bin/magento setup:static-content:deploy

I hope the above code help you.

  • Hi, can you elaborate on why you need to change something in the product grid? The above error occurs when saving an order. – simonthesorcerer May 18 at 12:47
