Hi @mahfuzurwp ,
I’ve had a deep dive into this as I was able to reproduce the problem locally. There appears to be a bug in WooCommerce in that it doesn’t recognise a legitimate s3:// file path.
In the function \WC_Product_CSV_Importer_Controller::file_is_in_directory the code calls new URL( $filepath) with the uploaded csv.
This breaks a valid S3 path like s3://s3-altis-dev/uploads/2025/02/product-sample_products-cug03qahbw.csv by changing it to file://s3/s3-altis-dev/uploads/2025/02/product-sample_products-cug03qahbw.csv
Can the team consider fixing this error in Product Import to support S3?
Thank you & regards,
Michael
