Invalid Parameter when trying to enhance a DSC resource

[Syl]

I’ve been doing mostly terraform for the last 18 months and now I need to modify a DSC resource(so, I’m rusty) and I’m facing a strange problem.  To solve a problem I added a parameter to an existing DSC resource(part of the xWebsiteAdministration resource) but when I try to run it  it doesn’t recognize the extra paramater as valid(It’s called from ansible, but it’s the same when trying it with invoke-dscresource)

“msg”: “Unsupported parameters for (ansible.windows.win_dsc) module: WebsiteName. Supported parameters include: Path, PsDscRunAsCredential_username, Filter, module_version, PsDscRunAsCredential_password, resource_name, OverrideMode, DependsOn”

I added the paramter the usual way

[Parameter(Mandatory = $true)]
[ValidateNotNullOrEmpty()]
[String]
$WebsiteName`

Any tips on what I am missing?  I looked at the rest of the code and didn’t see any other place to define a parameter.

Did you add an extra parameter to an existing resource in xWebAdministration module and calling it from ansible ?

[Syl]

Yes, that’s what I did

• added a parameter to xIisFeatureDelegation
• modified a line in the resource to use that parameter
• deployed the modified module to the test server
• called it using ansible(fail)
• called it locally using invoke-dscresource to see if it was ansible or the resource itself(still a fail, with same message that the new parameter is not a valid one for the resource)

EDIT: I made another reply with the code, but it seems to be stuck in moderation?.  Should appear eventually.

Here is the full command and result:

PowerShell

PS H:\> Invoke-DscResource -name xIisFeatureDelegation -Method Set -ModuleName xWebAdministration -Property @{filter = '/system.webserver/security/authentication/windowsAuthentication' >> OverrideMode='Allow' >> Path = 'IIS:\Sites\' >> WebsiteName = 'mywebsitename'}

1 2 3 4

PS H:\> Invoke-DscResource -name xIisFeatureDelegation -Method Set -ModuleName xWebAdministration -Property @{filter = '/system.webserver/security/authentication/windowsAuthentication' >> OverrideMode='Allow' >> Path = 'IIS:\Sites\' >> WebsiteName = 'mywebsitename'}

};^

and here is the parameter definition in the Set-TargetResource

PowerShell

   [CmdletBinding()]     param     (         [Parameter(Mandatory = $true)]         [ValidateNotNullOrEmpty()]         [String]         $Filter,         [Parameter(Mandatory = $true)]         [ValidateNotNullOrEmpty()]         [ValidateSet('Allow', 'Deny')]         [String]         $OverrideMode,         [Parameter(Mandatory = $true)]         [ValidateNotNullOrEmpty()]         [String]         $Path,         [Parameter(Mandatory = $true)]         [ValidateNotNullOrEmpty()]         [String]         $WebsiteName     )

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

[CmdletBinding()]     param     (         [Parameter(Mandatory = $true)]         [ValidateNotNullOrEmpty()]         [String]         $Filter,         [Parameter(Mandatory = $true)]         [ValidateNotNullOrEmpty()]         [ValidateSet('Allow', 'Deny')]         [String]         $OverrideMode,         [Parameter(Mandatory = $true)]         [ValidateNotNullOrEmpty()]         [String]         $Path,         [Parameter(Mandatory = $true)]         [ValidateNotNullOrEmpty()]         [String]         $WebsiteName     )
