Why is my CRON expression not accepted?

Question

I am trying to set up a rule that will create an issue every weekday at noon UTC. The below CRON expression is what I am trying to use:

0 0 12 ? * 2-6 *

However, when I try to publish the rule I get the below error:

Value -1 for dayOfMonth must be in the range [1,31]

The value I have set for dayOfMonth is '?' so that I can set the dayOfWeek to include only weekdays. How do I get my desired result?

Hi Jamie,

Sorry about this, but seems like you've run into a bug with the validation our cron library performs: https://codebarrel.atlassian.net/browse/AUT-130

For now can you try changing your CRON expression to:

0 0 12 ? * 2,3,4,5,6 *

Hope that helps!

Cheers,
  Andreas
