Job crontab bug, runs every minute

See original GitHub issue

Hi everyone,

I have 11 crontabs running in my backend but my last 5 crontabs have unexpected run time, just one of them start bugged and still this until node service restart

This is an example of one of them

cron.schedule('* * */2 * *', () => {
    console.log('Executing upload photo notification', new Date());
  });

The schedule is [* * */2 * *] it should run at every 2 hours but runs every minute

According to crontab.guru:

* * */2 * * : “At every minute on every 2nd day-of-month.” * */3 * * * : “At every minute past every 3rd hour.”

Is this the behaviour you’re observing?

@koenco thanks a lot for your inside, I’m aware I could misuse the pattern itself, so really thankful for help here. I would say this is pretty much like the behaviour I observe, but not what I wanted to achieve 😅
