Cannot search post by taxonomy

I’m trying to search posts by a taxonomy value, the problem is that the query doesn’t return anything, this is my code so far:

$args = array(
    'post_type' => 'zoacres-property',
    'post_status' => 'publish',
    'posts_per_page' => 10,
    'order' => 'DESC',
    'tax_query' => array(
        array(
            'taxonomy' => 'property-region',
            'field' => 'name',
            'terms' => array('Lazio (IT)'),
            'operator' => 'IN'
        )
    )
);

$query = new WP_Query($args);

This is the post record stored in the db:

wp_posts

 id    | post_title  | post_type
 30081      test         zoacres-property

the taxonomy property-region have that content:

wp_terms

term_id | name 
   62      Lazio (IT)

wp_term_taxonomy

term_taxonomy_id | term_id | taxonomy 
       62             62      property-region

wp_term_relationships

object_id | term_taxonomy
    30081       62

why my query isn’t returning anything?

UPDATE

output of $query->request:

SELECT SQL_CALC_FOUND_ROWS  wp_posts.ID FROM wp_posts  WHERE 1=1  AND ( 
  0 = 1
) AND wp_posts.post_type="zoacres-property" AND ((wp_posts.post_status="publish")) GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 10"

if I change the query as follows:

$args = array(
    'post_type' => 'zoacres-property',
    'post_status' => 'publish',
    'posts_per_page' => 10,
    'order' => 'DESC',
    'tax_query' => array(
        array(            
            'taxonomy' => 'property-region',
            'field' => 'term_id',
            'terms' => 2
        )
    )
);

I get as output:

"SELECT SQL_CALC_FOUND_ROWS  wp_posts.ID FROM wp_posts  LEFT JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) WHERE 1=1  AND ( 
  wp_term_relationships.term_taxonomy_id IN (2)
) AND wp_posts.post_type="zoacres-property" AND ((wp_posts.post_status="publish")) GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0, 10"

where 2 is the id of Lazio (IT), the post is published with that taxonomy linked. No idea why this doesn’t return anything
