How to use gocron to run a function at specific minutes every hour?

I tried two codes, one is dirty and the other doesn't work.

Dirty code:

loc, _ := time.loadlocation("asia/seoul")
    s := gocron.newscheduler(loc)

    _, err = s.every(1).day().at("0:30").do(schduler)
    _, err = s.every(1).day().at("1:30").do(schduler)
    _, err = s.every(1).day().at("2:30").do(schduler)
    _, err = s.every(1).day().at("3:30").do(schduler)
    _, err = s.every(1).day().at("4:30").do(schduler)
    _, err = s.every(1).day().at("5:30").do(schduler)
    _, err = s.every(1).day().at("6:30").do(schduler)
    _, err = s.every(1).day().at("7:30").do(schduler)
    _, err = s.every(1).day().at("8:30").do(schduler)
    _, err = s.every(1).day().at("9:30").do(schduler)
    _, err = s.every(1).day().at("10:30").do(schduler)
    _, err = s.every(1).day().at("11:30").do(schduler)
    _, err = s.every(1).day().at("12:30").do(schduler)
    _, err = s.every(1).day().at("13:30").do(schduler)
    _, err = s.every(1).day().at("14:30").do(schduler)
    _, err = s.every(1).day().at("15:30").do(schduler)
    _, err = s.every(1).day().at("16:30").do(schduler)
    _, err = s.every(1).day().at("17:30").do(schduler)
    _, err = s.every(1).day().at("18:30").do(schduler)
    _, err = s.every(1).day().at("19:30").do(schduler)
    _, err = s.every(1).day().at("20:30").do(schduler)
    _, err = s.every(1).day().at("21:30").do(schduler)
    _, err = s.every(1).day().at("22:30").do(schduler)
    _, err = s.every(1).day().at("23:30").do(schduler)
    if err != nil {
        fmt.println("error scheduling task:", err)
        return
    }
    s.startasync()

Code that doesn’t work:

_, err = s.Every(1).Hour().Minute(30).Do(runHourlyScheduler)

Workaround

Use .every(1).hour() and then chain it with .startat() and use Any time.time object that sets the minutes to 30 populates the argument.

This way, the scheduler will run for a few minutes every hour 30.

loc, _ := time.LoadLocation("Asia/Seoul")
s := gocron.NewScheduler(loc)

// construct start at in minute 30
now := time.Now()
nextSchedule := time.Date(now.Year(), now.Month(), now.Day(), now.Hour(), 30, 0, 0, now.Location())

_, err := s.Every(1).Hour().StartAt(nextSchedule).Do(schduler)
if err != nil {
    fmt.Println("Error scheduling task:", err)
    return
}

s.StartAsync()
