I'm getting the following error when running skaffold dev on my microservices project. I literally taken the code straight out of a tutorial on microservices, but am still getting the error:

The Deployment "orders-mongo-depl" is invalid: spec.selector: Invalid value: v1.LabelSelector{MatchLabels:map[string]string{"app":"orders-mongo"}, MatchExpressions:[]v1.LabelSelectorRequirement(nil)}: field is immutable
kubectl apply: exit status 1

Here is my "orders-mongo-depl.yaml" file

apiVersion: apps/v1
kind: Deployment
metadata:
  name: orders-mongo-depl
spec:
  replicas: 1
  selector:
    matchLabels:
      app: orders-mongo
  template:
    metadata:
      labels:
        app: orders-mongo
    spec:
      containers:
        - name: orders-mongo
          image: mongo

apiVersion: v1

  ports:

Here is my skaffold.yaml file

apiVersion: skaffold/v2alpha3

  kubectl:

      - ./infra/k8s/*

I have tried restarting skaffold, deleting and restarting Minikube, changing the minikube driver between virtualbox and docker, and restarting my computer. I am on the latest version of ubuntu and have up to date minikube, kubernetes and docker.
