"Type Error occurred when creating object: Magento\Eav\Model\Entity\Attribute\Source\Config"

I migrated from Magento 1.9.1.0 to Magento 2.3.1…the migration was completed with warnings and after I reindexed and flushed cache and also set upgrade, compile, and deploy, Clicking on All Customers at admin backend displays error, can’t view all customers and some customer information like the shipping address, billing address, contact, and name is missing from the order page.

I have remigrated countless times with different solutions but I still get the same error.

{“0″:”Type Error occurred when creating object:
MagentoEavModelEntityAttributeSourceConfig”,”1″:”#1
MagentoFrameworkObjectManagerFactoryCompiled->create(‘MagentoEavMode…’,
array()) called at
[vendor/magento/framework/ObjectManager/ObjectManager.php:56]

I was expecting the customer page should load properly and also view all customers shouldn’t be giving errors cos I have really gone through hell trying to solve this. I would be grateful for any assistance.

    Try to find the customer_eav_attribute that fronted_input column value is select in eav_attribute, make sure the column source_model is not NULL or empty or the value which refers to a specific class is correct.

    If it’s empty or NULL, you must be skip/ignore the error warning while migrating. You can solve this by changing the fronted_input column value to int until you finish creating the source_model class

    Try to debug this class MagentoCustomerModelMetadataCustomerMetadata specifically in the method getAttributeMetadata using xDebug. There you will find out which attribute_code that caused this error. And then as per @Idham Choudry, change the frontend_input value of that attribute in eav_attribute table. On my end, I changed it to text.
