Cannot bind argument to parameter 'Filter' because it is null

[glennvanbeneden]

Hi,

When using the xWebApplication resource I get the following error:

Cannot bind argument to parameter 'Filter' because it is null

When looking at the errors in the Event Viewer, I can find the following:

This event indicates that a non-terminating error was thrown when DSCEngine was executing Set-TargetResource on MSFT_xWebApplication DSC resource. FullyQualifiedErrorId is ParameterArgumentValidationErrorNullNotAllowed,Microsoft.IIs.PowerShell.Provider.SetConfigurationPropertyCommand. Error Message is Cannot bind argument to parameter 'Filter' because it is null..

MIResult: 1 Error Message: Destination element already exists, please use "force" parameter to override. Message ID: Destination element already exists, please use "force" parameter to override.,Microsoft.IIs.PowerShell.Provider.NewWebApplicationCommand Error Category: 5 Error Code: 5 Error Type: MI

The DSC configuration block I built looks like the following:

 WindowsFeature WebServer {
        Ensure = "Present"
        Name   = "Web-Server"
    }

    File "$($Instance)CommonFolder" {
        DestinationPath = "C:\inetpub\wwwroot\$($Instance)\Services\Common"
        Type            = "Directory"
    }

    xWebAppPool "$($Instance)CommonAppPool" {
        Name            = "$($Instance)_Common"
        Ensure          = "Present"
        State           = "Started" 
        autoStart       = $true
        startMode       = "OnDemand"
        loadUserProfile = $false
    }

    xWebApplication "$($Instance)CommonApplication" {
        Name               = "$($Instance)/Services/Common"
        WebAppPool         = "$($Instance)_Common"
        Website            = "Default Web Site"
        PhysicalPath       = "C:\inetpub\wwwroot\$($Instance)\Services\Common"
        Ensure             = "Present"
        AuthenticationInfo = MSFT_xWebApplicationAuthenticationInformation {
            Anonymous = $true
            Basic     = $false
            Digest    = $false
            Windows   = $true
        }
        DependsOn          = "[xWebAppPool]$($Instance)CommonAppPool", "[WindowsFeature]$($Instance)WebServer", "[File]$($Instance)CommonFolder"
    }
