What are common pitfalls when working with the $order variable in Woocommerce and how can they be avoided?

Common pitfalls when working with the $order variable in Woocommerce include not checking if the order object is valid before using it, not sanitizing and validating input data properly, and not handling errors or exceptions gracefully. To avoid these pitfalls, always check if the $order object exists and is valid before accessing its properties, sanitize and validate input data using Woocommerce functions, and use try-catch blocks to handle errors and exceptions. 

// Check if the $order object is valid before using it
if ( ! $order || ! is_a( $order, 'WC_Order' ) ) {
    return;
}

// Sanitize and validate input data
$order_id = absint( $_POST['order_id'] );

// Handle errors or exceptions gracefully
try {
    // Your code here
} catch ( Exception $e ) {
    // Handle the exception
}
