In wordpress 6.2 this function is deprecated

​

instead you can use it's definition with little bit of change

https://developer.wordpress.org/reference/functions/get_page_by_title/

​

function get_page_by_title(string $name, string $post_type = "post") {

    $query = new WP_Query([

        "post_type" => $post_type,

        "name" => $name

    ]);

​

    return $query->have_posts() ? reset($query->posts) : null;

}

now call get_page_by_title(<product_name>, 'product');

global $product;

$koostis = array_shift( wc_get_product_terms( $product->id, 'pa_koostis', array( 'fields' => 'names' ) ) );
