I am using Finch.stream to fetch a large CSV file from a server, but neither the ‘done’ state nor the ‘error’ state is being triggered when I use "{:halt, {:error, reason}}". I need help figuring out how to determine when the stream has finished fetching data.

Finch.build(:get, url, @headers)
    |> Finch.stream(
      Pdex.Finch,
      {"", {nil, nil}},
      fn
        {:status, status}, acc ->
          IO.inspect(status)
          {:cont, acc}

        {:headers, headers}, acc ->
          IO.inspect(headers)
          {:cont, acc}

        {:data, data}, acc ->
          {:cont, {:cont, {rest, _state} = order}} = acc

          chunk = rest <> data

          # {:halt, {:error, "force not work"}}

          {:cont, {chunk, state}}
       
        # never Geting Call
        {:error, reason}, acc ->
          IO.inspect(acc, label: "Error")
          {:halt, {:error, reason}}

        # never geting Call
        {:done, _}, acc ->
          IO.inspect(acc, label: "Done")
          {:ok, :done}
      end,
      receive_timeout: 30000
    )
  end
