Argo HTTP workflow - failed to get token volumes: service account argo/default does not have any secrets

I am new to Argo and following the Quickstart templates and would like to deploy the HTTP template as a workflow.

I create my cluster as so:

minikube start --driver=docker --cpus='2' --memory='8g'
kubectl create ns argo
kubectl apply -n argo -f https://raw.githubusercontent.com/argoproj/argo-workflows/master/manifests/quick-start-postgres.yaml

I then apply the HTTP template http_template.yaml from the docs:

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  generateName: http-template-
spec:
  entrypoint: main
  templates:
    - name: main
      steps:
        - - name: get-google-homepage
            template: http
            arguments:
              parameters: [ { name: url, value: "https://www.google.com" } ]
    - name: http
      inputs:
        parameters:
          - name: url
      http:
        timeoutSeconds: 20 # Default 30
        url: "{{inputs.parameters.url}}"
        method: "GET" # Default GET
        headers:
          - name: "x-header-name"
            value: "test-value"
        # Template will succeed if evaluated to true, otherwise will fail
        # Available variables:
        #  request.body: string, the request body
        #  request.headers: map[string][]string, the request headers
        #  response.url: string, the request url
        #  response.method: string, the request method
        #  response.statusCode: int, the response status code
        #  response.body: string, the response body
        #  response.headers: map[string][]string, the response headers
        successCondition: "response.body contains \"google\"" # available since v3.3
        body: "test body" # Change request body

argo submit -n argo http_template.yaml --watch

However I get the the following error:

Name:                http-template-564qp
Namespace:           argo
ServiceAccount:      unset (will run with the default ServiceAccount)
Status:              Error
Message:             failed to get token volumes: service account argo/default does not have any secrets

I'm not clear on why this doesn't work given it's straight from the Quickstart documentation. Help would be appreciated.

It seems your default serviceaccount is missing a credential (kubernetes secret)

You can verify the existence of the credential by checking which one it needs by running kubectl get serviceaccount -n default default -o yaml

kubectl get serviceaccount -n default default -o yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  creationTimestamp: "2022-02-10T10:48:54Z"
  name: default
  namespace: default
  resourceVersion: "*******"
  uid: ********************
secrets:
- name: default-token-*****

Now you should be able to find the secret which is attached to the serviceaccount

kubectl get secret -n default default-token-***** -o yaml

Or you can just run

kubectl get secret -n default

To see all secrets in the respective namespace (in this example, default)
