Knative: helloworld-go IngressNotConfigured

Question

I am quite new to knative, and I really need you guys' help. I was installing knative-serving by using YAML. My environment

multipass + k3s version v1.29.3+k3s1 (8aecc26b)
disabled traefik

Knative-serving Components & Networking layer & DNS & HPA Components knative-v1.13.1/serving-crds.yaml + knative-v1.13.1/serving-core.yaml Networking layer knative-v1.13.0/kourier.yaml DNS: magic DNS(sslip.io) knative-v1.13.1/serving-default-domain.yaml Serving Extension knative-v1.13.1/serving-hpa.yaml

Everything seems well at first, then I deployed a demon, and found default-domain-xxx pods always run into error. Detailed information are as follows. I have tried troubleshooting but didnot find similar circumsatnces. helloworld-go IngressNotConfigured

ubuntu@knative:~$ sudo kubectl get ksvc -n example
NAME            URL                                              LATESTCREATED         LATESTREADY           READY     REASON
helloworld-go   http://helloworld-go.example.svc.cluster.local/   helloworld-go-00001   helloworld-go-00001   Unknown   IngressNotConfigured

Networking Layer - Kourier looks fine

ubuntu@knative:~$ sudo kubectl -n kourier-system get service kourier
NAME      TYPE           CLUSTER-IP     EXTERNAL-IP    PORT(S)                      AGE
kourier   LoadBalancer   10.43.85.102   192.168.70.3   80:30407/TCP,443:31738/TCP   44h

But the serval pods run into error, like this

 ubuntu@knative:~$ sudo kubectl get pods -n knative-serving
NAME                                      READY   STATUS    RESTARTS      AGE

them I logs the error, but can't find solution, can you guys give me a clue? I would really really appreciate it.
