Running another mix task from Igniter

Let me start by saying i am very new to elixir in general and have just started messing around with Igniter.

I am trying to make an igniter task that runs another mix task, and I am running in to problems that I can’t figure my way out of after reading through some of the igniter docs/code. This is my igniter task:

  use Igniter.Mix.Task

  @shortdoc "makes a new project with user auth"

  def igniter(igniter, _argv) do
    igniter
      |> Igniter.add_task("phx.gen.auth", ["Accounts", "User", "users"])
  end
end

I am running it using:

mix igniter_example.gen.user_auth

And I am getting this error on running:

Compiling 1 file (.ex)
** (FunctionClauseError) no function clause matching in Application.ensure_all_started/2    
    
    The following arguments were given to Application.ensure_all_started/2:
    
        # 1
        [:rewrite]
    
        # 2
        :temporary
    
    Attempted function clauses (showing 1 out of 1):

    (mix 1.14.5) lib/mix/task.ex:421: anonymous fn/3 in Mix.Task.run_task/4
    (mix 1.14.5) lib/mix/cli.ex:84: Mix.CLI.run_task/2

Any help getting past this hurdle would be greatly appreciated.
