I'm trying to get cron expression to trigger an event at 7:45 UTC on only working days -- Monday to Friday.

45 7 * * MON,TUE,WED,THU,FRI *
45 7 * * 1,2,3,4,5 *

Although the above expressions were supposed to work I am getting an Invalid CRON expression error raised on both and so how is the day of the week supposed to be to get it to work on only working days?

Could you please try this

45 7 ? * MON,TUE,WED,THU,FRI *
45 7 ? * 1,2,3,4,5 *

or

45 7 ? * MON-FRI *
45 7 ? * 1-5 *
