Call to undefined method Magento\Eav\Model\Entity\Attribute\Backend\ArrayBackend::getAllOptions()

Fatal error: Uncaught Error: Call to undefined method Magento\Eav\Model\Entity\Attribute\Backend\ArrayBackend::getAllOptions() in /var/www/denta.loc/generated/code/Magento/Eav/Model/Entity/Attribute/Backend/ArrayBackend/Interceptor.php:36 Stack trace: #0 /var/www/denta.loc/vendor/magento/module-customer/Model/AttributeMetadataConverter.php(68): Magento\Eav\Model\Entity\Attribute\Backend\ArrayBackend\Interceptor->getAllOptions() #1 /var/www/denta.loc/vendor/magento/module-customer/Model/Metadata/CustomerMetadata.php(77): Magento\Customer\Model\AttributeMetadataConverter->createMetadataAttribute(Object(Magento\Customer\Model\Attribute)) #2 /var/www/denta.loc/vendor/magento/module-customer/Model/Metadata/CustomerMetadata.php(109): Magento\Customer\Model\Metadata\CustomerMetadata->getAttributeMetadata('default_blog_ca...') #3 /var/www/denta.loc/vendor/magento/module-customer/Model/Metadata/CachedMetadata.php(85): Magento\Customer\Model\Metadata\CustomerMetadata->getAllAttributesMetadata() #4 /var/www/denta.loc/vendor/magento/ in /var/www/denta.loc/generated/code/Magento/Eav/Model/Entity/Attribute/Backend/ArrayBackend/Interceptor.php on line 36

I found a fix adding the method getAllOptions which returns an empty array. Have any one encounter the same issue ( the db tables are populated ) and if so how did you fix it. Tank you!

According to the above exception the attribute "default_blog_ca..." cause the error. Try to remove it
