Took me a while to figure it out, but on current openiap ui, the cron placeholder has only 5 stars, not 6, which breaks the scheduler.

If you do something like `*/5 * * * *` it won’t work (fails silently), you have to append another start to have a valid cron expression e.g `*/5 * * * * *`.

It’s something very easy to miss
