If an incomplete address without the "country" information is inserted into an orderForm, items can't be added to it.

It happens because the shipping calculation depends on it, but while there are no items on the cart, this process isn't triggered, allowing invalid addresses to be registered.

It happens mostly through direct API usage. In internal logs, the exception may be found as "The Country field is required", under the 400 status code.

• to create an orderForm (without items yet)
• to add an address through the SendAttachment API (shippingData), without the country property
• to try adding an item; it'll generate a generic exception

It's required to ensure that every address contains the "country" information since the frontend implementation.
