Middleware don't work with IngressRoute

Issue

I want to use an IngressRoute with a Middleware but the middleware doesn't apply to my IngressRoute. Both are well created but the middleware is not attached to my IngressRoute. I have no error logs even with the DEBUG log level. Something strange, I also have no errors if I reference a non existing middleware.

Did I missed something?

What did you do?

I have the following resources:

apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: fixed-header
  namespace: production
spec:
  headers:
    customRequestHeaders:
      Host: "myhost.com"
---
apiVersion: traefik.containo.us/v1alpha1
kind: IngressRoute
metadata:
  annotations:
    name: blog
    namespace: production
  name: blog
  namespace: production
spec:
  entryPoints:
  - websecure
  routes:
  - kind: Rule
    match: Host(`myhost.com`) && PathPrefix(`/blog`)
    services:
    - port: 80
      name: blog
  middlewares:
    - name: production-fixed-header@kubernetescrd

Also tried with:

  middlewares:
  - name: fixed-header
    namespace: production

And also:

  middlewares:
  - name: non-existing
    namespace: production

In the tree cases, Traefik logged no erros.

What version of Traefik are you using?

2.5.1

I recommend to upgrade Traefik from 2.5.1 to 2.9.6 first.

Even with the latest version, I still have "There are no Middleware configured" on my route :slightly_frowning_face:

In addition, the Middleware is well added on the Ingress objects.

edit: I'm wondering, if this was an RBAC issue, would I have any errors?
