If you receive errors regarding the products when trying to import reviews, check if the product IDs included in your file are correct.
Either product_handle or product_id is required to import the reviews to Judge.me WooCommerce plugin.
You should also make sure that your products are correctly synced.
The product handle is the last part of the product URL. For example, for www.yourshop.com/products/red-widget, the product handle is red-widget.
To find the WooCommerce product ID of a product:
• Go to your WooCommcerce admin, Products tab
• Hover over any product to see the product ID (e.g. ID: 122)
