I added custom taxonomy to woocommerce plugin and i want to set archive page for it with pagination.
Here is my code

<?php



get_header();



// Get args to show list of sans in locations taxonomy page



$locations_tax = get_queried_object();



$paged = ( get_query_var('page') ) ? get_query_var('page') : 1;



$sans_args = array(

  'post_type' => 'product',

  'order'     => 'ASC',

  'posts_per_page' => 7,

  'paged'     => $paged,

  'tax_query' => array(

    array(

      'taxonomy' => 'locations',

      'field'    => 'term_id',

      'terms'    => $locations_tax->term_id

    )

  ),

);



$sans        = new WP_Query( $sans_args );

$sans_counts = count( $sans );



if ( $sans->have_posts() ) {



  $i = 0;



  echo '<ul class="nav nav-pills" id="pills-tab" role="tablist">';



  while ( $sans->have_posts() ) { $sans->the_post();



  ?>

  <li class="nav-item">

    <a class="nav-link <?php echo ($i==0)?'active':''; ?>" id="pills-<?php the_ID(); ?>-tab" data-toggle="pill" href="#pills-<?php the_ID(); ?>" role="tab" aria-controls="pills-<?php the_ID(); ?>" aria-selected="true"><?php the_title(); ?></a>

  </li>

  <?php



  $i++;



  }



  echo '</ul>';



  wp_pagenavi( array( 'query' => $sans ) );



  wp_reset_postdata();



}



get_footer();



?>

The pagination show but when i click on second page i got 404 page.
I tried some solution on stackoverflow but doesn't work for me.
Sorry for my bad english
