Order With Extension Not Working

I am having an issue with getting the order moved over to Alibaba Express when someone orders from the website. The order is listed under the AliExpress orders in my website however when I click on the Order With Extension it goes to the AliExpress portal to place an order I get, Sorry, the page you requested cannot be found. I verified that the product is available and can order on the website manually. In the corner of the page a red banner show, Can not add products to cart.
