Problem async Tasks from other module

Hello everybody, I’m creating an app service aggregator, I created some modules, my idea it’s one module create tasks and inside other module create the await and select only one task, after you select one task you will be get a mutex, but this is another history. So I’m using this modules, one is “App” and another is “Driver”, when you add the name of app, It goes to create some Task async, the names that I’m gonna use, are created by a random name creation line. Until now it’s working well, the issue comes, when I try to execute the async from another module, says that I’m sending two arguments, I modified the function to get two params but not works, how can I get this async from other modules ? =D thanks my friends

defmodule Tarea2 do

  defmodule App do

    @app Apps

    #### Start agent
    def start do
      Agent.start_link(fn -> %{} end,  name: @app)
    end

    #### Start tasks from app
    def task(app) do
      for x <- 0..4 do
        name = Enum.take_random(alphabet = Enum.to_list(?a..?e), 5)
        :timer.sleep(1000)
        name = Task.async(fn ->
              pid = self()
              ms = Enum.random(1..1000)
              info = "Codigo #{name} : Hernan Cuy, lugar x lugar y, 20000"
              Agent.update(@app, fn state -> Map.put(state, x, info) end)
              :timer.sleep(120000)
              IO.puts "#{inspect(pid)} finished in #{ms}ms"
              Agent.update(@app, fn state -> Map.delete(state, x) end)
          end)
      end
    end

    #### getNotifications
    def getNotifications do
      Agent.get(@app, fn state -> Map.values(state) end)
    end

    def taskReceiver(name) do
      Task.await(name)
    end

  end

  defmodule Central do

    @name __MODULE__

    #### Start the principal agent
    def start do
      Agent.start_link(fn -> {} end,  name: @name)
    end

    #### Add apps and start tasks
    def aggregator(app) do
      Agent.update(@name, fn state ->
        Tuple.append(state, app)
      end)

      Tarea2.App.task(app)
    end

    #### Get all apps
    def getApps do
      Agent.get(@name, fn state -> state end )
    end

  end

  defmodule Driver do
    @mut MutexRegion

    defstruct [name: "John", matricula: 28]

    def aggregator(app) do
      Tarea2.Central.start
      Tarea2.App.start
      Tarea2.Central.aggregator(app)
    end

    def taskReceiver do
      msg = Tarea2.App.getNotifications
    end

    def selectTask do
      taskSelected = String.trim(IO.gets("Ingrese codigo de solicitud a atender: "))
      Tarea2.App.taskReceiver(taskSelected)
      #Mutex.await(@defstruct, mutex2_id)
      #Process.sleep(1000)
      #Mutex.release(@defstruct, mutex1_id)
    end

  end

end

Here the error
