[SOLVED] What is wrong about this AWS cron ScheduleExpression?

Issue

Trying to run the schedule every monday at 8:15, I tried the following expression:

cron(15 8 * * MON *)

I thought this means:

• Minutes: 15
• Hour: 8
• Day-of-month: Every *
• Month: Every *
• Day-of-week: Monday only
• Year: Every

Documentation: http://docs.aws.amazon.com/AmazonCloudWatch/latest/events/ScheduledEvents.html

Solution

Following the same link, your mistake is related with this restriction:

Limits

• You can't specify the Day-of-month and Day-of-week fields in the same Cron expression. If you specify a value in one of the fields, you must use a ? (question mark) in the other.

So, fix it using:

cron(15 8 ? * MON *)
