Hello there,

I inherited a rather complicated LiveComponent from a colleague: due to complex JS there’s no render/1 function, only update/2.
I have a hook which publishes an event to said component, which should then start an async operation on the backend.

  @impl true
  def handle_event("classify-users", _params, socket) do
    socket =
      socket
      |> start_async(:perform_classification, fn ->
        raise "Some error"
      end)

    {:noreply, socket}
  end

I expect this code to eventually call the handle_async callback:

 @impl true
  def handle_async(:perform_classification, {:exit, reason}, socket) do
    Logger.error("Could not perform classification: #{reason}")
    {:noreply,
     push_event(socket, "classification-finished", %{class: "Error #{reason}"})}
  end

However, the component simply crashes and I don’t know why it never executes said handle_async function.
Any idea?
