Magento 2.4.4 sample data installation error

[akhilesh4u66f7]

I have downloaded Magento version 2.4.4 with sample data from https://magento.com/tech-resources/download I was trying to install it on the Wamp server. But when I run the installation I get the error

Unable to apply data patch Magento\GroupedProductSampleData\Setup\Patch\Data\InstallGroupedProductSampleData for module Magento_GroupedProductSampleData. Original exce
  ption message: Rolled back transaction has not been completed correctly.

I tried with versions 2.4.3 and 2.4.3-p2 all are showing the same error. But I was able to install the 2.4.3 version without sample data. I searched and found it is related to some error in the csv file. But none of the answers provided a solution. Please help.

Hello @akhilesh4u66f7 ,

This issue is with syntax issue of sample CSV files which are located at :

Spoiler

/vendor/magento/module-catalog-rule-sample-data/fixtures/catalog_rules.csv /vendor/magento/module-sales-rule-sample-data/fixtures/sales_rules.csv

Fix the above CSVs manually or online tool.

for ex : https://csvlint.io/

Hope it helps !
