I am trying to use Drupal webforms with tokens to build out a redirect url for my form submissions. Everything works great when all fields are populated, but if a field is left empty the redirect does not happen. Promo code is an optional field. This is with Webform 6.x-3.14

Redirect URL: %value[app_url]/user/new?email=%value[email_address]&first_name=%value[first_name]&last_name=%value[last_name]&promo_code=%value[promo_code]
