User registration error after migration

Question

After Migration from Magento 1.9.2.4 to Magento 2.3.4 when I go to create a customer and fill all the information and click on submit(on front-end), it shows me an error

We can't save the customer.

After debugging I found the error below:

Class Magento\Eav\Model\Attribute\Data\Datetime does not exist

I tried to search the class on the database and also in files, with no results. However, I found something similar in the table eav_attribute:

Magento\Eav\Model\Entity\Attribute\Backend\Datetime

How can I solve it?

Answer 1

Please open this file

vendor\magento\module-customer\Controller\Account\CreatePost.php

And then replace

$this->messageManager->addException($e, $e->getMessage());

With this code

$this->messageManager->addException($e, __('We can\'t save the customer.'));

So, you can get actual error and you can trace it.

Happy Coding.
