Nebulex error: (Nebulex.RegistryLookupError) could not lookup Nebulex cache Payment.Cache because it was not started

I am getting the below error. I am just practicing Nebulex and have followed the instructions given in the how-to-cache-locally-in-elixir-with-nebulex

 (Nebulex.RegistryLookupError) could not lookup Nebulex cache Payment.Cache because it was not started or it does not exist
    (nebulex 2.6.3) lib/nebulex/cache/registry.ex:22: Nebulex.Cache.Registry.lookup/1

Is that started as a child in your Application start function?

defmodule NebulexPrac.Application do
  use Application

  def start(_type, _args) do
    children = [Payment.Cache]

    opts = [strategy: :one_for_one, name: NebulexPrac.Supervisor]
    Supervisor.start_link(children, opts)
  end
end

Is the Payment.Cache module under the NebulexPrac namespace? You need to pass the full name (unless you alias it)

defmodule NebulexPrac.Application do
  use Application

  def start(_type, _args) do
    children = [NebulexPrac.Payment.Cache] # Here it needs to be the full module name

    opts = [strategy: :one_for_one, name: NebulexPrac.Supervisor]
    Supervisor.start_link(children, opts)
  end
end
