PowerShell Command Set-PasswordFilterConfig fails

[PVTGoesen]

Version: 1.1.51
I used an elevated shell:

PS C:\...> Import-Module LithnetPasswordProtection
PS C:\...> Set-PasswordFilterConfig -StorePath "C:\LPPforAD"

Set-PasswordFilterConfig : Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.
In Zeile:1 Zeichen:1
+ Set-PasswordFilterConfig -StorePath "C:\LPPforAD"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Set-PasswordFilterConfig], NullReferenceException
    + FullyQualifiedErrorId : System.NullReferenceException,Lithnet.ActiveDirectory.PasswordProtection.PowerShell.SetP
   asswordFilterConfig

Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt. Is german for:
object reference not set to an instance of an object

I tested it on Windows Server 2012R2, 2019 and 2022.

Does this command just change the registry key?
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Lithnet\PasswordFilter
REG_SZ - Store - C:\...

Or do I need to change something else as well?

@PVTGoesen
Thanks for reporting this bug and apologies for any inconvenience caused.

If you create an empty registry key HKLM\Software\Policies\Lithnet\PasswordFilter this issue should go away.

We will get a new release published shortly to fix this.

And yes, the PowerShell script just changes that key.

Hi, thanks for the answer. I changed it manualy and it works fine.

Fixed in v1.1.53
