I am a newbie to Shopify, i am facing error when i click on to add to cart and also all my item description are missing
1. My client have existing store in UAT instance without any issue and I export theme, product, inventory, customer
2. I create a new store in myshopify and import theme, product, inventory, customer. And i create similar collection, discount, etc.
3. When i try to simulate purchase a product from the website, it shown error 'Parameter Missing or Invalid: Required parameter missing or invalid: items'
4. Then i create a new product to do the simulation, the same errors occurs
5. I also notice all of the product I have imported missing the 'Description' and 'Details' information.
