[SOLVED] ValidationException: Parameter ScheduleExpression is not valid

Issue

My cron syntax is

cron(25 8 10 2 4 2022)

And I wish to run the job exactly once on Thursday February 10 at 8:25 am. But getting the above error when trying to run.

Solution

You can schedule lambda event using following syntax:

# NOTE: This will execute on UTC mode only
cron(Minutes Hours Day-of-month Month Day-of-week Year)

So your cron expression should look like:

cron(25 08 10 02 ? 2022)
