I’m struggling with a routing problem. I’ve added a slug-field to the TCA and added the configuration to the config.yaml. In the frontend the urls are generated correctly but when I click on the Link the default 404 error page shows up.

This is the routeEnhancer in the config.yaml

  TracepartsDetail:
    type: Extbase
    extension: Traceparts
    plugin: Api
    limitToPages:
      - 348
      - 569
      - 429
      - 472
      - 473
      - 475
    routes:
      - routePath: '/api/{product_slug}'
        _controller: 'Traceparts::show'
        _arguments:
          product_slug: product
    defaultController: 'Traceparts::index'
    aspects:
      product_slug:
        type: PersistedAliasMapper
        tableName: tx_traceparts_domain_model_product
        routeFieldName: path_segment

And this is the fluid template.

<f:link.action action="show" controller="Traceparts" extensionName="Traceparts" pluginName="Api" arguments="{product:product.repositoryProduct.uid}">{product.apiProduct.title}</f:link.action>

If I change the routeFieldName to “uid” everything works fine.
Any idea whats wrong? Or at least how to debug?

Kind regards, Cornel
