When trying to create account getting the following error:
Type Error occurred when creating object: Magento\Eav\Model\Entity\Attribute\Source\Config, Argument 1 passed to Magento\Eav\Model\Entity\Attribute\Source\Config::__construct() must be of the type array, null given, called in /home/admin/web/projects.thesst.com/public_html/SIS953_M2/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 121
Same error in both frontend and backend and unable to create or login the customers.
Please disable the third-party extensions that are related to customers.
Hi @Sanjay Jethva
Thanks for the reply.
I have solved it for temporary by changing the customer attribute tax_class_id frontend_input type from select to text in eav_attribute table.
Please suggest what will the source_model class need to give instead of NULL for this tax_class_id attribute in eav_attribute table.
