cScheduleTask - The RepetitionInterval and RepetitionDuration Job trigger parameters must be specified together

[Zuldan]

The config below for cScheduledTask worked perfectly fine in 3.7.8.1...

cScheduleTask PowershellHelpUpdateScheduledTask
{
    Ensure                           = 'Present'
    PsDscRunAsCredential             = $Credential
    TaskName                         = 'Powershell Help Update'
    Runlevel                         = 'Highest'
    Compatibility                    = 'Win8'
    Hidden                           = $False
    Disable                          = $False
    Execute                          = 'powershell.exe'
    Argument                         = "-NoProfile -Command `"Update-Help -SourcePath $($Node.PowershellHelpSource) -Module * -Force -ErrorAction SilentlyContinue`""
    TaskPath                         = '\'
    ScheduledAt                      = [DateTime]"2016/02/13 $($Time.Hour):$($Time.Minute):00" # Saturday
    RepetitionIntervalTimeSpanString = [TimeSpan]::FromDays(7).ToString() # run every week
    RepetitionDurationTimeSpanString = [TimeSpan]::MaxValue.ToString() # to forever
}

...but in 3.7.8.3 the following error appears...

Invoke-CimMethod : PowerShell DSC resource Grani_ScheduleTask  failed to execute Set-TargetResource functionality with error message: The RepetitionInterval and RepetitionDuration Job trigger parameters must be specified together.

What a shame. Checking....

ok. Issue seems to be haapen when target OS is Windows Server 2012 R2 or lower. Will not happen on Windows Server 2016 and Win10.

Win2016 and Win10

And is due to change on ver.3.7.8.3 as Zuldan suspect.

@Zuldan To ensure issue, can you kindly clarify your Lab OS Version?

[guitarrapc]

@Zuldan I've fixed and publish ver.3.7.8.4 to PowerShell Gallery. https://www.powershellgallery.com/packages/GraniResource/3.7.8.4

It is appreciated if you can check at your lab.

@guitarrapc, thanks so much for getting it fixed so quickly. I'm using 2012 R2 in my lab. It's working now with version 3.7.8.4.
