How to change custom categories term links?

I have created "Tour Vacation"(tour-vacation) custom taxonomy and added below terms

• Africa (africa)
• Canada (canada)
• Europe (europe)
• US (us)

I want change this terms links.

Current link is: /

I want to change it to: /

So i have done below code.

add_filter( 'term_link', 'change_term_link', 10, 3 );
function change_term_link( $url, $term, $taxonomy ) {
  if ( 'tour-vacation' === $taxonomy ) {
    $url = home_url() . '/vacation-pacakge/' . $term->slug.'-tour';
  }
  return $url;
}

The link is changing but it's showing "404 page not found error"
