Error when creating Knative Service: Admission webhook denied request due to metadata.name change validation

[helloxjade]

Description: I encountered an issue when trying to create a new Knative Service. Even though the service is newly created, I receive an error related to the validation of the metadata.name in spec.template. The error suggests that the service is attempting a change without a corresponding name update, which is unexpected for a newly created resource.

Error Message:

Failed to create Knative Service: admission webhook "validation.webhook.serving.knative.dev" denied the request: validation failed: Saw the following changes without a name change (-old +new): spec.template.metadata.name...

Expected Behavior: As this is a new service creation, there should be no conflict or validation errors on metadata.name in spec.template.

Steps to Reproduce:

"sigs.k8s.io/controller-runtime/pkg/controller/controllerutil"
if _, err := controllerutil.CreateOrUpdate(ctx, ksb.KnativeClient, knservice, ksb.MutateKnServiceFn(knservice, sapp)); err != nil {
// 如果不是资源版本冲突错误，记录事件和日志
if !apierrors.IsConflict(err) {
ksb.EventRecorder.RecordEventf(sapp, corev1.EventTypeWarning, util.EventReasonFailedCreateKsvc, util.FailedCreateKsvcMsg, err.Error())
klog.Errorf("Failed to create or update knservice for app: %s, error: %v", sapp.Name, err)
}
// 返回错误，触发重试机制
return err
}
If applicable, mention whether CreateOrUpdate with mutate functions was used and if the mutation involved changes to metadata.
Environment:

Knative version: v1.11.4
Kubernetes version: Kubernetes v1.25.14

Any insight into this validation behavior or recommended configurations to avoid this error would be helpful. Thanks!
