"Shipping address is not set" error when saving cart

Question

I have a simple code, where i add a simple product to the cart

$cart = $obj->get('\Magento\Checkout\Model\Cart');
$cart->addProduct(5, 3);
$cart->save();

but the last row, returns this error: Fatal error: Uncaught Magento\Framework\Exception\StateException: Shipping address is not set

Why is necessary to add a shipping address to save the cart?

How i can add an address programmatically?

Answer 1

\Magento\Checkout\Model\Cart' class has been deprecated from100.1.0`.

Use \Magento\Quote\Model\Quoteinstead Please check https://github.com/magento/magento2/commit/e5479b4e7b87b8ad22dc1ca8e4c33556999da5f2

You can add shipping address programmatically by following code..!

=> event.xml

    <?xml version="1.0"?>
    <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
        <event name="sales_quote_save_after">
            <observer name="sales_quote_save_after_event" instance="Test\Module\Observer\SalesQuoteSaveAfter" />
        </event>
    </config>

=> Test/Module/Observer/SalesQuoteSaveAfter.php

    <?php

    namespace Test\Module\Observer;

    use Magento\Framework\Event\ObserverInterface;

    class SalesQuoteSaveAfter implements ObserverInterface
    {
        protected $addressFactory;

        public function __construct(\Magento\Quote\Api\Data\AddressInterface $address) 
        {
            $this->address = $address;
        }

        public function execute(\Magento\Framework\Event\Observer $observer)
        {
            $quote = $observer->getEvent()->getQuote();

            if (!$quote->hasItems()) 
            {
                $quote->setBillingAddress($this->getEmptyAddress())->setShippingAddress($this->getEmptyAddress());
            }
        }

        private function getEmptyAddress() 
        {
            $this->address->setRegionId(0);
            $this->address->setRegion("");
            $this->address->setRegionCode("");
            $this->address->setCountryId("");
            $this->address->setStreet([""]);
            $this->address->setCompany("");
            $this->address->setTelephone("");
            $this->address->setFax("");
            $this->address->setPostcode("");
            $this->address->setCity("");
            $this->address->setFirstname("");
            $this->address->setLastname("");
            $this->address->setMiddlename("");
            $this->address->setEmail("");
            $this->address->setSameAsBilling(1);
            $this->address->setSaveInAddressBook(0);
            return $this->address;
        }
    }
