If you are getting errors saying that your country cannot be blank, even though you have data for that field, It's most often related to your Shopify shipping settings. First up, verify that:
- Billing address country can’t be blank
- Shipping Address country can’t be blank
If both fields are filled in and you still get this error, then you may need to temporarily enable international shipping during the import:
To enable international shipping:
Settings > Shipping
Create a zone for “rest of world” if one does not already exist
