Get-PnPAzureADUser: This cmdlet does not work with a ACS based connection towards SharePoint

[BrianMichely]

Hey folks,
We are running some power automate inventory scripts, and part of a script attempts to get flow information. There is an AAD app registration with the correct permissions to SPO. Script is attached.

Script does run the following:
Add-PowerAppsAccount
Connect-PnPOnline -Url $spotenanturl -Tenant $tenantid -ClientId $appid -Thumbprint $certthumbprint

But on line 83 it runs:
$flowuser = Get-PnPAzureADUser -Identity $theflow.CreatedBy.userId -ErrorAction SilentlyContinue

and throws this error:
Get-PnPAzureADUser: This cmdlet does not work with a ACS based connection towards SharePoint

Customer is running this from a VM jumpbox.

Any help would be greatly appreciated.
