Minimal Example Code Reproducing the Issue

const bot: Telegraf<Context<Update>> = new Telegraf(config.telegramBotToken);
bot.use(async (ctx, next) => {
  if (ctx.from && config.allowedUsers.includes(ctx.from.id.toString())) {
    await next();
  } else {
    ctx.reply("Sorry, you are not allowed to use this bot.");
  }
});

bot.use(async (_, next) => {
  const start = dayjs();
  await next();
  const ms = dayjs().diff(start);
  console.log("Response time: %sms", ms);
});

bot.launch();

cron.schedule("*/15 * * * *", async () => {
  const msg = `-= Heartbeat ${dayjs.utc().format("HH:mm")} UTC =-`;
  try {
    bot.telegram.sendMessage(config.telegramChatId, msg);
  } catch (error) {
    console.log("schedule error:", error);
  }
});

process.once("SIGINT", () => {
  bot.stop("SIGINT");
});
process.once("SIGTERM", () => {
  bot.stop("SIGTERM");
});
