Getting error with "Administrators" security type in SPServiceAppSecurity

Details of the scenario you try and problem that is occurring: I’m trying to execute this code:

Configuration Example 
{
    param(
        [Parameter(Mandatory = $true)]
        [PSCredential]
        $SetupAccount
    )
    Import-DscResource -ModuleName SharePointDsc

    node localhost {
        $membersToInclude = @()
        $membersToInclude += MSFT_SPServiceAppSecurityEntry {
                                Username    = "CONTOSO\SharePointFarmAccount"
                                AccessLevel = "Full Control"
                            }
        $membersToInclude += MSFT_SPServiceAppSecurityEntry {
                                Username    = "CONTOSO\SharePointServiceApps"
                                AccessLevel = "Full Control"
                            }
        SPServiceAppSecurity UserProfileServiceSecurity
        {
            ServiceAppName       = "User Profile Service Application"
            SecurityType = "Administrators"
            Members  = $membersToInclude
            PsDscRunAsCredential = $SetupAccount 
        }
    }
}

I’m receiving the following error:

Cannot bind argument to parameter 'ReferenceObject' because it is null.
    + CategoryInfo          : InvalidData: (:) [], CimException
    + FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Microsoft.PowerShell.Commands.CompareObje
   ctCommand

When I look in the MOF file, I can see that there is no empty value. Everything is well populated. Perhaps I’m doing something wrong but I don’t see what. I didn’t try to use ‘MembersToInclude’ and use ‘Members’ instead because I want to make sure that only the list provided is admin on the service and no one else.

@BrianFarnhill Sure. I will open another issue for the “doing nothing” matter. Thanks

I guess this is registered in issue #641, which is still open.
