forceSlash option depreciated in 3.x - how to work around for access to dashboard

Traefik Traefik v3 (latest)

Having upgraded from traefik 2.8.2 to 3.4.1 I have run into an issue with the forceSlash option being depreciated (Traefik V3 Migration Details - Traefik). My 2.8.2 router had the configuration below to reach the dashboard page. This would allow me to match the ansible variable {{ inventory_hostname }} eg dev001.staging.example.com/traefik and send the request to the dashboard.

  middlewares:
    traefikAcp:
      stripPrefix:
        forceSlash: true
        prefixes:
          - /traefik
  routers:
    api:
      entryPoints:
        - http
        - https
      rule: (Host(`{{ inventory_hostname }}`) && PathPrefix(`/api`)
      service: api@internal
      tls: {}
    dashboard:
      entryPoints:
        - http
        - https
      middlewares:
        - traefikAcp
      rule: (Host(`{{ inventory_hostname }}`) && PathPrefix(`/traefik`)
      service: api@internal
      tls: {}

Post upgrade to traefik 3.4.1, that now returns a 404 against dev001.staging.example.com/traefik. In order to get the to dashboard I have to add a training slash, so dev001.staging.example.com/traefik/

I tried the configuration below, but this also results in a 404 (when called as /traefik).

      stripPrefix:
        prefixes:
          - /traefik
      addPrefix:
        prefix: /
  routers:
    api:
      entryPoints:
        - http
        - https
      rule: (Host(`{{ inventory_hostname }}`) && PathPrefix(`/api`)
      service: api@internal
      tls: {}
    dashboard:
      entryPoints:
        - http
        - https
      middlewares:
        - traefikAcp
      rule: (Host(`{{ inventory_hostname }}`) && PathPrefix(`/traefik`)
      service: api@internal
      tls: {}

Any suggestions on how I can modify this such that /traefik (rather than /traefik/) will render the dashboard page?

Thanks,

In Traefik v3 you can set the path for the dashboard (doc), different from /. Have you tried that instead of stripPrefix?

Note that by default both paths /dashboard and /api are required.
