I have docker image in my repo, akshay123007/lists-pods. I have created helm chart image:

  # Overrides the image tag whose default is the chart appVersion.
  tag: ""

  # Specifies whether a service account should be created
  create: true
  # Annotations to add to the service account
  annotations: {}
  # The name of the service account to use.
  # If not set and create is true, a name is generated using the fullname template
  name: ""

resources: {}
  # We usually recommend not to specify default resources and to leave this as a conscious
  # choice for the user. This also increases chances charts run on environments with little
  # resources, such as Minikube. If you do want to specify resources, uncomment the following
  # lines, adjust them as necessary, and remove the curly braces after 'resources:'.

  #   cpu: 100m

when i install chart ,i get error as: Failed to pull image "akshay123007/lists-pods:1.16.0": rpc error: code = Unknown desc = Error response from daemon: manifest for akshay123007/lists-pods:1.16.0 not found: manifest unknown: manifest unknown.

I have tried changing image:docker.io/akshay123007/lists-pods:latest, then it says errImagePull.I dont what is the issue, any help would be appreciated.
