How do I invoke Pipeline.handle_info from a Phoenix.WebChannel?

Nope, I updated the code to:

  @impl true
  def handle_init(_) do
    spec =
      child(:source, AudioTranscription.Source)
      |> child(:sink, %Membrane.File.Sink{location: "output.wav"})

      {[spec: spec], %{}}
  end

  @impl true
  def handle_info(audio_data, ctx, state) do
    # Process the audio data
    {[notify_child: {:source, audio_data}], state}
  end

  @impl true
  def handle_init(_) do
    spec =
      child(:source, AudioTranscription.Source)
      |> child(:sink, %Membrane.File.Sink{location: "output.wav"})

      {[spec: spec], %{}}
  end

  @impl true
  def handle_info(audio_data, ctx, state) do
    # Process the audio data
    {[notify_child: {:source, audio_data}], state}
  end

I'm still getting:

[error] <0.768.0>/ Error occured in Membrane Pipeline:
%Membrane.UnknownChildError{
  message: "Child of name :source doesn't exist. Available children are [].\n"

[error] <0.768.0>/ Error occured in Membrane Pipeline:
%Membrane.UnknownChildError{
  message: "Child of name :source doesn't exist. Available children are [].\n"

Also, now I'm getting another error:

 Error occured in Membrane Pipeline:
%Membrane.UnknownChildError{
  message: "Child of name AudioTranscription.Source doesn't exist. Available children are [].\n"
}

 Error occured in Membrane Pipeline:
%Membrane.UnknownChildError{
  message: "Child of name AudioTranscription.Source doesn't exist. Available children are [].\n"
}

Is this the wrong way to define specify children?

  @impl true
  def handle_init(_) do
    spec =
      child(AudioTranscription.Source)
      |> child(%Membrane.File.Sink{location: "output.wav"})

      {[spec: spec], %{}}
  end

  @impl true
  def handle_init(_) do
    spec =
      child(AudioTranscription.Source)
      |> child(%Membrane.File.Sink{location: "output.wav"})

      {[spec: spec], %{}}
  end
