When trying to import Customers from the backend, Data validation is OK but when I click on import button, the page gets stuck on please wait for loader and I get the error :

See the logs below

Apr 24 16:20:01 web9 ool www: PHP Fatal error: Uncaught Error: Call to a member function getBackendModel() on null in /var/www/staging-vhosts/timberland.co.za/vendor/magento/module-customer-import-export/Model/Import/Customer.php:442#012Stack trace:#012#0 /var/www/staging-vhosts/timberland.co.za/vendor/magento/module-customer-import-export/Model/Import/Customer.php(517): Magento\CustomerImportExport\Model\Import\Customer->_prepareDataForUpdate(Array)#012#1 /var/www/staging-vhosts/timberland.co.za/vendor/magento/module-import-export/Model/Import/AbstractEntity.php(640): Magento\CustomerImportExport\Model\Import\Customer->_importData()#012#2 /var/www/staging-vhosts/timberland.co.za/vendor/magento/module-import-export/Model/Import.php(441): Magento\ImportExport\Model\Import\AbstractEntity->importData()#012#3 /var/www/staging-vhosts/timberland.co.za/vendor/magento/module-import-export/Model/Import.php(412): Magento\ImportExport\Model\Import->processImport()#012#4 /var/www/staging-vhosts/timberland.co.za/vendor/magento/framework/Interception/Interceptor.php(58): Magento\ImportE in /var/www/staging-vhosts/timberland.co.za/vendor/magento/module-customer-import-export/Model/Import/Customer.php on line 442

Can you please advise as to what could be the cause of this issue, is there any way I can get all customer attribute, so I can see what attribute is causing this.

Thanks

  • have you tried importing it locally and debug it? – Philipp Sander Apr 24 at 14:34
  • I have tried importing locally but i'm getting the same error, seems to be something to do with customer attributes but i don't know where to start looking into this – K Kazadi Apr 24 at 14:43
  • ok. and have you tried debugging it? – Philipp Sander Apr 24 at 14:44
  • How do i do that? I'm still new to Magento 2 – K Kazadi Apr 24 at 15:15
  • xdebug. just how you debug any other php applications. there are plenty tutorials outthere that teach you how to configure xdebug – Philipp Sander Apr 24 at 15:32
