Answer 1

After a long and hectic time spend on this issue finally I found the solution for this:

First Go to phpmyadmin for magento2 database and run the below query:

SELECT * FROM `eav_entity_type` WHERE `increment_model` = 'Magento\\Eav\\Model\\Entity\\Increment\\Numeric'

Now run the below queries to update the increment_model:

UPDATE `avanteksrv_mage207`.`eav_entity_type` SET `increment_model` = 'Magento\\Eav\\Model\\Entity\\Increment\\NumericValue' WHERE `eav_entity_type`.`entity_type_id` =1;
UPDATE `avanteksrv_mage207`.`eav_entity_type` SET `increment_model` = 'Magento\\Eav\\Model\\Entity\\Increment\\NumericValue' WHERE `eav_entity_type`.`entity_type_id` =5;
UPDATE `avanteksrv_mage207`.`eav_entity_type` SET `increment_model` = 'Magento\\Eav\\Model\\Entity\\Increment\\NumericValue' WHERE `eav_entity_type`.`entity_type_id` =6;
UPDATE `avanteksrv_mage207`.`eav_entity_type` SET `increment_model` = 'Magento\\Eav\\Model\\Entity\\Increment\\NumericValue' WHERE `eav_entity_type`.`entity_type_id` =7;
UPDATE `avanteksrv_mage207`.`eav_entity_type` SET `increment_model` = 'Magento\\Eav\\Model\\Entity\\Increment\\NumericValue' WHERE `eav_entity_type`.`entity_type_id` =8;

conclusion: we need to update the increment_model from Magento\Eav\Model\Entity\Increment\Numeric to Magento\Eav\Model\Entity\Increment\NumericValue

Happy coding!!
