Get product weight from Wordpress

Question

The code below is used to get data on a products of the category "books" in my Wordpress website using Woocommerce.

<?php
 $args = array( 'post_type' => 'product', 'posts_per_page' => 200, 'product_cat' => 'books');
       $loop = new WP_Query( $args );


    $send_array = array();
       while ( $loop->have_posts() ) : $loop->the_post(); 
        global $product; 

    $send_array[] = array(

        'id' => get_the_ID(),
        'title' => get_the_title(),
        'content' => get_the_content(),
        'regular_price' => get_post_meta( get_the_ID(), '_regular_price', true),
        'sale_price'=> get_post_meta( get_the_ID(), '_sale_price', true),
        'weight' => woocommerce_get_product_terms($product->id, 'weight', 'names')

    );

     endwhile; 

     wp_reset_query(); 
        ob_clean();
        echo json_encode($send_array);
        exit();

    ?>

This works fine and returns the data correctly except for the weight attribute.

This is a custom attribute set in my website using Woocommerce. In my database the weight attribute shows up in the wp_woocommerce_attribute_taxonomies table. This table has the fields attribute_id, attribute_name, attribute_label etc.

The code I used above to get the weight value of the product doesn't work.

I also tried 'weight' => get_post_meta( get_the_ID(), '_weight', true), but it shows up as an empty string (weight:"") even though that product has a Weight value on the website.

How do I get the weight for each product and add it to the array to the key weight as I have attempted above.

Have been doing some research and this seemed to be the item to work. What am I doing wrong?

How do I fix this?

global $product;    
$product->get_weight();
