401 Error using PnP PowerShell in Azure Runbooks
Trying to get PnP PowerShell cmdlets to work within an Azure Runbook with modern authentication (no username/password). I tried registering an Azure AD app and a Service Principal (Run as account) from the automation account that hosts the Runbook. Both use a certificate thumbprint and authorization itself doesn't throw an error. Here's the code I'm using: $connection = Get-AutomationConnection –Name "AzureRunAsConnection" $tenant = '[tenant].onmicrosoft.com' $url = 'https://[tenant].sharepoint.com/sites/test' Connect-PnPOnline -Url $url –Thumbprint $connection.CertificateThumbprint –ClientId $connection.ApplicationID -Tenant $tenant For every PnP cmdlet this throws the following error. Get-PnPTenantSite : The remote server returned an error: (401) Unauthorized. At line:7 char:1 + Get-PnPTenantSite + ~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Get-PnPTenantSite], WebException + FullyQualifiedErrorId : System.Net.WebException,PnP.PowerShell.Commands.GetTenantSite I have also updated the cmdlets from SharePointPnPPowerShellOnline to the newest PnP.PowerShell. Furthermore, the Azure app and service principal are members of the SharePoint administrators group. When I attempt to reproduce the issue on a local machine I get the same 401 error. Any ideas? Thanks!Solved7.5KViews0likes3Comments
