Magento 2.4: create CSV File for each order placed - magento2

Question

I am new to magento. I need to automatically create a csv file whenever an order is placed by the customer.
I am using the event "sales_order_place_after" but the code in the observer is not working.
Can anyone guide me how to generate the csv file successfully whenever the order gets placed.
i keep getting errors like: Object of class Magento\Sales\Model\Order\Address could not be converted to string
Class Order implements ObserverInterface
{
protected $_request;
protected $_order;
protected $_productRepository;
protected $_scopeConfig;
protected $_customer;
protected $_storemanager;
public function __construct(
\Magento\Framework\App\RequestInterface $request,

$this->directory = $filesystem->getDirectoryWrite(DirectoryList::VAR_DIR);
$this->_productRepository = $productRepository;
}
public function execute(\Magento\Framework\Event\Observer $observer) {
$order = $observer->getEvent()->getOrder();
$websiteID = $this->_storemanager->getStore()->getWebsiteId();
$headers = array( 'Customer Name', 'Customer Email', ' Phone','Shipping Address' ,'SKU','Quantity','Price','Total','Weight');
$name = strtotime('now');
$file = 'customorderexport/'.$name.'_detailed_orderexport.csv';
$this->directory->create('customorderexport');
$stream = $this->directory->openFile($file, 'w+');
$stream->lock();
$stream->writeCsv($headers);
// $orderdetail['Customer Name'] =
$orderdetail['Customer Email'] = $order->getCustomerEmail();
$orderdetail['Contact Phone'] = $order->getTelephone();
$orderdetail['Shipping Address'] = $order->getShippingAddress();
$items = $order->getAllItems();
foreach ($items as $item) {
$orderdetail['SKU'] = $item->getSKU();
$orderdetail['Quantity'] = $item->getQtyOrdered();
$orderdetail['Price'] = $item->getPrice();
$orderdetail['Total'] = $item->getGrandTotal();
$orderdetail['Weight'] = $item->getWeight();
$stream->writeCsv($orderdetail);
}
$stream->unlock();
$stream->close();
}
}

Answer 1

This is because
$order->getShippingAddress();
will return a OrderAddressInterface object. (Magento\Sales\Api\Data\OrderAddressInterface)
You could do following for example:
$shippingAddress = $order->getShippingAddress();
$orderdetail['Shipping Address'] = $shippingAddress->getStreet()[0];
