🐞 Calling Dagger.Client.host/1 fails

[gmile]

What is the issue?

Dagger.Client.host/1 function is advertised in docs, however calling it fails with an following error, and so is fails Dagger.Host.directory/2 (so I must be doing something wrong here):

# removed for brevity
Compiling 3 files (.ex)
    warning: Dagger.Host.directory/2 is undefined (module Dagger.Host is not available or is yet to be defined)

Dagger version

v0.12.3

Steps to reproduce

Create and cd into a sample directory:

mkdir dagger-module-sample && cd dagger-module-sample

Initialize new Elixir module:

dagger init --sdk=github.com/dagger/dagger/sdk/elixir/runtime .

Find the main module file and replace it with this contents:

defmodule DaggerModuleSample do
  use Dagger.Mod, name: "DaggerModuleSample"

  defstruct [:dag]

  @function [
    args: [],
    return: Dagger.Container
  ]
  def problem(self, args) do
    host_tmp =
      self.dag
      |> Dagger.Client.host()
      |> Dagger.Host.directory("/tmp")

    self.dag
    |> Dagger.Client.container()
    |> Dagger.Container.with_directory("/tmp", host_tmp)
  end
end
