Reporting an Issue or Missing Feature

I get an issue when I try either Get-PnPSiteDesign or Get-PnPSiteScript in order the get the list of designs (or scripts)
I tried as well specifying the Id of script or design but get the same NullReferenceException

FYI, I just noticed that only happens when I connect using WebLogin (with my admin account),
with direct credentials, it works just fine

I can confirm that I'm seeing the same error when using UserWebLogin

Connect-PnPOnline -Url "https://<TENANT>.sharepoint.com/<PATH>/<SITE>" -UseWebLogin;
Get-PnPConnection;

The error message returned is:

Get-PnPSiteDesign : The remote server returned an error: (403) Forbidden.
At line:1 char:1

• Get-PnPSiteDesign

•   + CategoryInfo          : NotSpecified: (:) [Get-PnPSiteDesign], WebException
    + FullyQualifiedErrorId : System.Net.WebException,SharePointPnP.PowerShell.Commands.GetSiteDesign
  

But it works fine when using Credentials

Connect-PnPOnline -Url "https://<TENANT>.sharepoint.com/<PATH>/<SITE>" -Credentials (Get-Credential);
Get-PnPConnection;

Is there any progress in a fix?

UPDATE #1 - WORK AROUND

To get the Get-PnPConnection to work with UserWebLogin you need to connect to your SharePoint Admin site like so:

Connect-PnPOnline -Url "https://<TENANT>-admin.sharepoint.com" -UseWebLogin;
Get-PnPConnection;

This does mean that PnP example below is not good, as you would applying the site design to the SharePoint Admin Center...

Get-PnPSiteDesign | ?{$_.Title -eq "Demo"} | Invoke-PnPSiteDesign

Instead you could do something like this:

Connect-PnPOnline -Url "https://<TENANT>-admin.sharepoint.com" -UseWebLogin;
$siteDesign = Get-PnPSiteDesign | ?{$_.Title -eq $row.SiteDesignName};
Invoke-PnPSiteDesign -Identity $siteDesign.Id -WebUrl "https://<TENANT>.sharepoint.com/<PATH>/<SITE>";

Noting forgetting to disconnect of cause :)

Disconnect-PnPOnline;

Update #2

Apparently Add-PnPSiteDesignTask has superseded the above CmdLet, see Microsoft's documentation for more info:
