Describe the bug
The cron expressions described in this documentation doesn't work, and received the following error.
Failed to instantiate schedule for nodejs function
Caused By: Cron field for month must be a whole number between 1 and 12\nCron expressions cannot have both day-of-month and day-of-week defined, you must use a ? in one of the fields\nCron field for month must be a whole number between 1 and 12\nCron expressions cannot have both day-of-month and day-of-week defined, you must use a ? in one of the fields
It seems that the validateCron function doesn't accept the * wildcard.
Reproduction steps
Follow the documentation to set the schedule for a function.
