Hi @Aveeva,

Can you please first cross check whether you have duplicate entries for the "product-details" keyword in database in eav_attribute_group.

If you dont have duplicate records then can you please try doing migration on fresh magento 2  database. Seems like you have tried migration multiple times.

Hope this helps you!

Yes, in my database already available that column name?

Hi @Aveeva,

If you have duplicate entries then you need to delete entries and keep only one.

Thanks!

Hi @Aveeva 

Go to the location below and add the empty data condition to the Rule.php file. 

vendor/magento/module-sales-rule/Model/ResourceModel/Rule.php line 352

wrap it in

if (!empty($data)) {
    $connection->insertMultiple($this->getTable('salesrule_product_attribute'), $data);
}

After adding the condition, run the command below via SSH in the root of you Magento installation: php bin/magento setup:upgrade


It may help you!

Hi @Aveeva,

Did you try your data migration command with --reset parameter.?

I found something related to your issue: can you also try the same if possible.
