How ignore or exclude synchronize resources

[roc26002w]

I'm add applicate to sync exists k8s

run command line :
argocd app sync my-k8s-app --async

• fetch sync fails:

how can I ignore this resource sync or resolve this fail?

this is my ignoreDifferences but not working

ignoreDifferences:
- group: apiextensions.k8s.io
  jsonPointers:
  - /status
  kind: CustomResourceDefinition
  name: cloudflare-issuer.clusterissuers.cert-manager.io
- group: apiextensions.k8s.io
  jsonPointers:
  - /status
  kind: cert-manager.io/v1/ClusterIssuer
  name: cloudflare-issuer

.........

syncPolicy:
  syncOptions:
  - Validate=false
  - CreateNamespace=true
  - RespectIgnoreDifferences=true
  - ApplyOutOfSyncOnly=true
  - SkipDryRunOnMissingResource=true
  - Prune=false

The ignoreDifferences and RespectIgnoreDifferences prevent argocd from syncing unchanged resources but it won't help if resource is not permitted in a project (this check is executed first). I think you won't have to use config management tool settings to exclude resources. If you are using helm then you might use skipCrds: true:

spec:
  source:
    # helm specific config
    helm:
      skipCrds: true
