This item is not an AliExpress product or it was deleted

Hello, I am placing a test order to check my payment gateway is working correctly. I’ve spent a lot of time setting up the product pages after importing them as variable products. I’ve used one of the test card details and when I check the order under the plugin in the admin dashboard, I am getting the error “This item is not an AliExpress product or it was deleted” – I viewed the product and checked the external ID and it is pointing to the correct product.
