WooCommerce get category slug - Undefined property notice with a function

I use this function to convert the woocommerce category id into a category slug

function woocommerceCategorySlug($id){
$term = get_term( $id, 'product_cat' );
return $term->slug;

This is working, but the problem is that i'm getting a notice

Notice: Undefined property: WP_Error::$slug

Is there a way to avoid this notice?


The working solution for this is to use WordPress native function get_term_by() and to transpose it in your code this way:

function woocommerceCategorySlug( $id ){
    $term = get_term_by('id', $id, 'product_cat', 'ARRAY_A');
    return $term['slug'];
