Windows Server

Error: Failed to create new Scheduled Task RemoteException: Exception calling UpdateTriggers RemoteException: You cannot call a method on a null-valued expression. RemoteException: Cannot validate argument on parameter Xml – daily task ok but monthly not

The following error displayed below is a result of a bug in the Windows Admin Center. I was able to successfully create a scheduled task on a monthly basis in my lab environment as shown below

I found this error was reported also in Windows Server user-voice
– Note: Daily tasks can be created, edited, run and deleted successfully.

This issue comes up when you select the trigger on a monthly (monthlyDOW) basis. I am sure this will be fixed soon.–bug-not-add-new-scheduled-scheduled-tasks
