  ms: number
) =>
  new Promise<void>((resolve) => {
    setTimeout(() => {

    }, ms);
  });


export const retryFunc = async (

    return;
  }
  const bo = await func(currentCount);
  if (bo) {
    return;
  }
  await sleep(waitingMillisecond);
  await retryFunc(count, waitingMillisecond, func, currentCount + 1);
