You mean like sample below? Apparently the reference to script.exs is lost as well.

iex(4)> Code.eval_string(
  """
  fun = fn ->
    raise "RAISE"
    List.flatten([])
  end

  Task.async(fn ->
    try do
      fun.()
    rescue
      e -> {e, __STACKTRACE__}
    end
  end) |> Task.await(:infinity)
  """,
  [],
  file: "script.exs"
)

{{%RuntimeError{message: "RAISE"},
[
  {:elixir, :eval_external_handler, 3,
   [file: ~c"src/elixir.erl", line: 386, error_info: %{module: Exception}]},
