Why can't create products from array in woo rest api?

Question

WooCommerce

Why is it impossible to create products from an array?

The code:

<?php 
// $max_tover = count($result->products);
// for ($i = 1; $i <= count($result->products); $i++)
// {
//   $hi_products[$i] = array(
//   'name' => $arr_tovar[$i]->name, 
//   'status' => 'pending', 
//   'categories' => array(
//       array( 
//           'id_iiko_категории' => $arr_tovar[$i]->productCategoryId 
//       )
//   ),
//   'regular_price' => $arr_tovar[$i]->price );
// }
$arr_tovar = $result->products;
    $params = [
        'headers' => array(
            'Authorization' => 'Basic ' . base64_encode( 'admin:123123123' )
        ),
        'body' => [],
    ];
/*
   'body' => array(
     'name' => 'My test2', 
     'status' => 'pending', 
     'categories' => array(
       array( 
         'id' => 15 
       )
     ),
     'regular_price' => '9.99' 
     // more params http://woocommerce.github.io/woocommerce-rest-api-docs/?shell#product-properties
   )*/
   
    foreach ($arr_tovar as $item) {
         $params['body'][] = array(
            'name' => $item->name, 
            'status' => 'pending', 
            'categories' => array(
                array( 
                    'id_iiko_категории' => $item->productCategoryId 
                )
            ),
            'price' => $item->price
        );
    }

    $api_response = wp_remote_post( $url_site.'/wp-json/wc/v3/products', $params);

    $body = json_decode( $api_response['body'] );
    if( wp_remote_retrieve_response_message( $api_response ) === 'Created' ) {
       echo 'Этот продукт ' . $body->name . ' успешно создан';
    }else{
        echo 'Ошибка'. wp_remote_retrieve_response_message( $api_response );
    }
    
    echo '<pre> $body: <br>';
    var_dump( $body );
    echo '</pre><br><br>';
    echo '<pre> $params["body"]<br>';
    var_dump( $params['body'] );
    echo '</pre>';

?>

var_dump( $body ); outputs:

Because you don’t need to read stupid and not very tutorials if you can’t find an error in them yourself and debug the code. It's no offense, it's just a fact.
There are docks, everything is extremely accessible there.
https://woocommerce.github.io/woocommerce-rest-api...
And this Well, trash, you don’t need to call variables and array elements in Cyrillic, and in this case, you just need id there ["id_iiko_категории"]
