appinfo is not passed while running the pod-delete experiment

[soumyaparui]

I am using Chaos Chart version 3.1.0 on AKS. The installation and setup verifications are fine as the the below document: Getting Started with Litmus

But when I am running the following experiment:

apiVersion: litmuschaos.io/v1alpha1
kind: ChaosEngine

  namespace: nginx
spec:
  appinfo:
    appns: 'nginx'
    applabel: 'app=nginx'

  # It can be true/false
  #annotationCheck: 'false'
  # It can be active/stop
  engineState: 'active'
  #ex. values: ns1:name=percona,ns2:run=nginx
  auxiliaryAppInfo: ''
  chaosServiceAccount: pod-delete-sa
  # It can be delete/retain
  jobCleanUpPolicy: 'retain'
  experiments:
    - name: pod-delete
      spec:
        components:
          env:
            # set chaos duration (in sec) as desired
            - name: TOTAL_CHAOS_DURATION
              value: '30'

            # set chaos interval (in sec) as desired
            - name: CHAOS_INTERVAL
              value: '10'

            # pod failures without '--force' & default terminationGracePeriodSeconds
            - name: FORCE
              value: 'false'

             ## percentage of total pods to target
            - name: PODS_AFFECTED_PERC
              value: ''

Always the test is failing with the error: Fail Step: [chaos]: Failed inside the chaoslib, err: please provide one of the appLabel or TARGET_PODS
