title: RouteEnhancer with aspects throws InvalidParameterException
body: <p>I used the example verbatim from the <a href="https://docs.typo3.org/typo3cms/extensions/core/Changelog/9.5/Feature-86365-RoutingEnhancersAndAspects.html#persistedaliasmapper" rel="nofollow noreferrer">Changelog</a>:</p>
  
  <p>The only thing I changed was the limitToPages. </p>
  
  <pre><code>routeEnhancers:
    NewsPlugin:
      type: Extbase
      limitToPages: [82]
      extension: News
      plugin: Pi1
      routes:
        - { routePath: '/{news_title}', _controller: 'News::detail', _arguments: {'news_title': 'news'} }
      defaultController: 'News::detail'
      aspects:
        news_title:
          type: PersistedAliasMapper
          tableName: 'tx_news_domain_model_news'
          routeFieldName: 'path_segment'
          routeValuePrefix: '/'
  </code></pre>
  
  <p>This throws an exception in 9.5.4:</p>
  
  <pre><code>Symfony\Component\Routing\Exception\InvalidParameterException
  Parameter "tx_news_pi1__news" for route "tx_news_pi1_0" must match "[^/]++" ("" given) to generate a corresponding URL.
  
  in /var/www/example/htdocs/typo3_src-9.5.4/vendor/symfony/routing/Generator/UrlGenerator.php line 155
  
  
  at Symfony\Component\Routing\Generator\UrlGenerator-&gt;doGenerate(array('tx_news_pi1__news' =&gt; 0), array('_controller' =&gt; 'News::detail'), array(), array(array('variable', '/', '[^/]++', 'tx_news_pi1__news', true), array('text', '/aktuelles/artikel')), array('tx_news_pi1__news' =&gt; ''), 'tx_news_pi1_0', 1, array(), array())
  in /var/www/example/htdocs/typo3_src-9.5.4/vendor/symfony/routing/Generator/UrlGenerator.php line 128
  </code></pre>
  
  <p>Currently, no other route enhancers exist. But I successfully used a simpler configuration on that exact same page and that worked:</p>
  
  <pre><code>NewsDetail:
    type: Extbase
    limitToPages: [82]
    extension: News
    plugin: Pi1
    routes:
      - { routePath: '/{news_id}', _controller: 'News::detail', _arguments: {'news_id': 'news'} }
  </code></pre>
  
  <p>Not sure where to look and how best to troubleshoot. I was hoping someone had similar problem or could point me in the right direction.</p>
