I am getting below error while trying to apply patch :

I am able to reproduce the issue in my test environment. Steps to reproduce:
You are able to view the YAML file here and here is the sample:
---
apiVersion: "apps/v1"
kind: "Deployment"
metadata:
name: "nginx-1"
namespace: "default"
labels:
app: "nginx-1"
spec:
replicas: 3
selector:
matchLabels:
app: "nginx-1"
template:
metadata:
labels:
app: "nginx-1"
spec:
containers:
- name: "nginx"
image: "nginx:latest"
---
apiVersion: "autoscaling/v2beta1"
kind: "HorizontalPodAutoscaler"
metadata:
name: "nginx-1-hpa"
namespace: "default"
labels:
app: "nginx-1"
spec:
scaleTargetRef:
kind: "Deployment"
name: "nginx-1"
apiVersion: "apps/v1"
minReplicas: 1
maxReplicas: 5
metrics:
- type: "Resource"
resource:
name: "cpu"
targetAverageUtilization: 80
After deployment if you go to Kubernetes Engine > Workloads > nginx-1 (click on it)
a.) You will get Deployment details (Overview, Details, Revision history, events, YAML)
b.) click on YAML and copy the content from YAML tab
c.) create new YAML file and paste the content and save the file
d.) Now if you run the command $kubectl apply -f newyamlfile.yaml, it will shows you the below error:

To solve the problem, you need to find the exact yaml file and then edit it as per your requirement, after that you can run $kubectl apply -f nginx-1.yaml
Hope this information finds you well.
