check if node exists in restore resource modifier

[0R9H3U5]

I am attempting to modify a couple ingress values in all ingresses using the restore-resource-modifier. This is a fairly large application which has many components deployed by third party helm charts so there are some inconsistencies in the yaml of the various ingresses.

I am running into a situation where some ingress definitions do not include /spec/tls/0/hosts/0 or even the /spec/tls node at all. Most ingresses do though. Is there a way to check if the node exists and log a warning instead of marking the restore as partially failed?

I have tried using test operation with a value of .* which still results in errors in the restore and a partially failed designation

spec:  
  ingressClassName: nginx  
  tls:  
    - hosts:  
        - example.com  
  rules:
    - host: example.com
      http:

vs

spec:
  ingressClassName: nginx
  rules:
    - host: example.com

I think the way to tdo that is to break down your restore to smaller number of components. Perhaps at backup time label which item has /0/host/0 then you can backup separately ones that do and do not.

I do like this idea as then I could use the labelSelector in the restore resource modifier conditions. I would still need to find a way to determine which ingresses do not have /spec/tls/0/hosts/0 programmatically.

Short of getting the yaml for each ingress and using yq or something to check for the specific node I am not having much luck in doing that. kubectl patch using a test operation has not been successful yet
kubectl patch ingress myingress --type='json' -p='[{"op": "test", "path": "/spec/tls/0/hosts/0"}]' -n somens
