service_navigation HTML is as expected

Code
  service_navigation(links = c("Page 1", "Page 2", "Page 3"))
Output
  <section aria-label="Service information" class="govuk-service-navigation" data-module="govuk-service-navigation">
    <div class="govuk-width-container">
      <div class="govuk-service-navigation__container">
        <nav aria-label="Menu" class="govuk-service-navigation__wrapper">
          <button type="button" class="govuk-service-navigation__toggle govuk-js-service-navigation-toggle" aria-controls="navigation" hidden="TRUE">Menu</button>
          <ul class="govuk-service-navigation__list" id="navigation">
            <li class="govuk-service-navigation__item">
              <a class="action-button action-link govuk-service-navigation__link" href="#" id="page_1"><span class="action-label">Page 1</span></a>
            </li>
            <li class="govuk-service-navigation__item">
              <a class="action-button action-link govuk-service-navigation__link" href="#" id="page_2"><span class="action-label">Page 2</span></a>
            </li>
            <li class="govuk-service-navigation__item">
              <a class="action-button action-link govuk-service-navigation__link" href="#" id="page_3"><span class="action-label">Page 3</span></a>
            </li>
          </ul>
        </nav>
      </div>
    </div>
  </section>

Code
  service_navigation(service_name = "My app", c(`Page 1` = "p1", `Page 2` = "p2",
    `Page 3` = "p3"))
Output
  <section aria-label="Service information" class="govuk-service-navigation" data-module="govuk-service-navigation">
    <div class="govuk-width-container">
      <div class="govuk-service-navigation__container">

          </ul>
        </nav>
      </div>
    </div>
  </section>

service_navigation works with a single link

Code
  service_navigation(links = "Solo page")
Output
  <section aria-label="Service information" class="govuk-service-navigation" data-module="govuk-service-navigation">
    <div class="govuk-width-container">
      <div class="govuk-service-navigation__container">
        <nav aria-label="Menu" class="govuk-service-navigation__wrapper">
          <button type="button" class="govuk-service-navigation__toggle govuk-js-service-navigation-toggle" aria-controls="navigation" hidden="TRUE">Menu</button>
          <ul class="govuk-service-navigation__list" id="navigation">
            <li class="govuk-service-navigation__item">
              <a class="action-button action-link govuk-service-navigation__link" href="#" id="solo_page"><span class="action-label">Solo page</span></a>
            </li>
          </ul>
        </nav>
      </div>
    </div>
  </section>
