I don't have handle_info defined in my LiveView, but there is no error thrown when a message is sent

Questions / Help

I have a pretty standard show.ex from the generators:

defmodule AppWeb.TaskLive.Show do
  use AppWeb, :live_view

  alias App.Tasks

  @impl true
  def mount(_params, _session, socket) do
    {:ok, socket}
  end

  @impl true
  def handle_params(%{"id" => id}, _, socket) do
    {:noreply,
     socket
     |> assign(:page_title, page_title(socket.assigns.live_action))
     |> assign(:task, Tasks.get_task!(id))}
  end

  defp page_title(:show), do: "Show Task"
  defp page_title(:edit), do: "Edit Task"
end

A message is being sent to it by a form component on save and edit:

defp notify_parent(msg), do: send(self(), {__MODULE__, msg})

But there is no error thrown, even though there is no handle_info defined in the live view. Is there a handle_info automatically defined somewhere in Phoenix? Any documentation of this behavior I could look at?

Something changed in the develop branch and now it’s giving the expected error of no function clause matching in TaskLive.Show. Can’t seem to figure out why it’s working on main, as the handle_info is not there.

Thank you!
