TypeInitializationException and InvalidCastException thrown when calling LithnetRMA from an execution controller

[johnyukloud]

When I invoke Lithnet Resource Management PS from MA executor, it would fail on

Set-ResourceManagementClient -BaseAddress "http://localhost:5725";

there is error in the application eventlog about System.TypeInitializationException: The type initializer for 'Lithnet.ResourceManagement.Client.ResourceManagementClient' threw an exception.

Seems it is not able to access the configure file when executed from the MA executor.

The code I executed as follow:

function ExecutionComplete
{
	param([Lithnet.Miiserver.Client.RunDetails]$lastRunDetails)
        
	# If the run was an import an a change was made, create the MACD report
	foreach ($step in $lastRunDetails.StepDetails)
	{
		if ($step.StepDefinition.Type -eq 'FullImport'){		
			Set-ResourceManagementClient -BaseAddress "http://localhost:5725";
			
			$terminatedPortalUsers = Search-Resources -Xpath "/Person[(EmployeeEndDate > op:subtract-dayTimeDuration-from-dateTime(fn:current-dateTime(), xs:dayTimeDuration('P1D'))) and (EmployeeEndDate < fn:current-dateTime())]" -AttributesToGet @("AccountName","EmployeeEndDate","EmployeeID")

			$terminatedPortalUsers | Export-Csv "C:\temp\test1.txt" -notype
			
			$psons = Get-MVObject -ObjectType person
			$psons | Export-Csv "C:\temp\test2.txt" -notype
		}
	}
}

The error in the eventlog as below:

Ascender SQL MA: ExecutionComplete handler threw an exception
System.ApplicationException: The PowerShell script encountered an error
at ExecutionComplete, : line 20
System.TypeInitializationException: The type initializer for 'Lithnet.ResourceManagement.Client.ResourceManagementClient' threw an exception. ---> System.InvalidCastException: [A]Lithnet.ResourceManagement.Client.ClientConfigurationSection cannot be cast to [B]Lithnet.ResourceManagement.Client.ClientConfigurationSection.

what is the proper way to execute Lithnet Resource Management PS from MA executor from the Executor MA?

I have tried to wrap around the call inside a script block, it works but the Get-MVObject would fail, it would return

The Synchronization Service Manager service has stopped.

when the Synchronization Service Manager service is actually running.

@johnyukloud this is definitely a bug, but a complex one to solve. I'll look to resolve this in v2. In the mean time, the workaround would be to launch a new instance of PowerShell to run the fim service query such as shown in this example https://stackoverflow.com/questions/23237473/powershell-launch-script-in-new-instance

You seem to be referencing another issue with Get-MVObject. That is from a different PowerShell module. Can you provide more information about the context of the issue you are having there?

@johnyukloud I'm working on the fix for this, but I've got a cleaner workaround you can use in the mean time. Edit the Lithnet.Miiserver.AutoSync.exe.config file and remove the following two lines

<section name="lithnetResourceManagementClient" type="Lithnet.ResourceManagement.Client.ClientConfigurationSection, Lithnet.ResourceManagement.Client"/>

and

<lithnetResourceManagementClient resourceManagementServiceBaseAddress="http://localhost:5725"/>

This will prevent the error you are seeing. These lines are not needed for AutoSync or the PowerShell module to work.

@johnyukloud i'm marking this issue as done. You can apply the workaround above, or install the latest version of LithnetRMA from https://github.com/lithnet/resourcemanagement-powershell/releases/tag/v1.0.6623

If you are still having issues with Get-MVObject, please open a new issue, and we work on that one separately, as it is unrelated to what is going on here.

Great! Thanks Ryan
