Скрипт systemd для уведомления-отправки завершается с ошибкой «Соединение закрыто»

Question

Я пытаюсь запустить системный таймер. Я публикую все соответствующие файлы и ошибку ниже. Я разместил файл nodejs, но я попытался использовать простой сценарий оболочки, а также объяснил в разделе «Правка».

get-combined-notification.js

      const util = require("util");
const stdExec = require("child_process").exec;
const exec = util.promisify(stdExec);

const appNameForDunst = "CombinedNotification";
const executeScript = async (shellCommand) => {
  return await exec(shellCommand);

const notifySendCommand = async (text) =>
  await executeScript(
    `notify-send -t 5000 -a ${appNameForDunst} " " ${JSON.stringify(
      text
    )}`
  );

const commands = [
  {
    title: "Battery",
    command: "acpi -b",
    process: 'return output.split(",")[1]',
  },
  {

    process: "return output",

    process:
      'return ["view", "dev", "servers", "config", "notes", "av"][output.trim().substr(-1)]',
  },
  {
    title: "Date",
    command: "date '+ %a %d %b %y%nTime:   %I:%M'",
    process: "return output",

  {

let final = "";

const handler = async (command, index) => {
  const result = await executeScript(command.command);
  const processOutput = new Function("output", command.process);
  final = final + `${command.title}: ${processOutput(result.stdout)}\n`;
};

const main = async () => {
  await Promise.allSettled(commands.map(handler));
  notifySendCommand(final);
};
main()

Редактировать:

Чтобы исключить nodejs как виновника, я использовал сценарий оболочки с одной строкойnotify-send "some" "some" вместо скрипта nodejs. Я получаю ту же ошибку в журнале:sh[2607]: The connection is closed
