So we are using kustomize to patch a yaml file and with kubectl version 1.20.0 it works fine . the moment we use with kubectl 1.21 it gives the error

command executed
kubectl kustomize > test.yaml

Error: no matches for IdId ~G_v1_ServiceAccount|reloader|reloader-reloader; failed to find unique target for patch ~G_v1_ServiceAccount|reloader-reloader

here is are all the files
resource.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  annotations:
    meta.helm.sh/release-namespace: "default"
    meta.helm.sh/release-name: "reloader"
  labels:
    app: reloader-reloader
    chart: "reloader-v0.0.77"
    release: "reloader"
    heritage: "Tiller"
    app.kubernetes.io/managed-by: "Tiller"
  name: reloader-reloader

patch.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  annotations:
    meta.helm.sh/release-namespace: "default"
    meta.helm.sh/release-name: "reloader"
  labels:
    app: reloader-reloader
    release: "reloader"
    heritage: "Tiller"
    app.kubernetes.io/managed-by: "Tiller"  
  name: reloader-reloader
  namespace: reloader

here is the kustomization file
kustomization.yaml

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
namespace: reloader
resources:
  - resource.yaml
patchesStrategicMerge:
  - patches.yaml

Any help here please

I believe I am running into the same issue. Reproducible on both kubectl 1.21.1 and 1.21.3 for me
