Connect-PnPOnline - On Prem Tranformation

[pkbullock]

When connecting to SharePoint 2013 with latest PnP version (2.12.0)

I am getting
"Connect-PnPOnline: Specified method is not supported."

Example:
$sp13Conn = Connect-PnPOnline -Url http://portal2013/en -Credentials OnPrem -ReturnConnection -TransformationOnPrem

Note:

powershell/src/Commands/Base/PnPConnection.cs

Line 455 in 572d697

internal static PnPConnection CreateWithCredentials(Cmdlet cmdlet, Uri url, PSCredential credentials, bool currentCredentials, string tenantAdminUrl, bool persistLogin, System.Management.Automation.Host.PSHost host, AzureEnvironment azureEnvironment = AzureEnvironment.Production, string clientId = null, string redirectUrl = null, bool onPrem = false, InitializationType initializationType = InitializationType.Credentials)

Please assign to me :-) I have a test rig back operational to investigate transform issues.

Reverting to version 2.4.0 allows connect.... oh wait I had my VM pause. Will validate with latest version shortly 🤦‍♂️

Confirmed, not working in 2.12.0

Just for notes

Question for the maintainers: I'm confused when seeing reports about SP OnPrem whether PnP PowerShell still supports them or not, as the readme on the homepage states "This version of the cmdlets is cross-platform (i.e it works on Windows, MacOS and Linux) but it will only support SharePoint Online." .

Is the idea to support only certain scenarios, like page transformation, or should every issue related to OnPrem be closed as "not supported" ?
