Problems with .update() method to change conditional access policy for SPO site using PNP.

Question

Hello,

I am trying o change conditional access policy for SharePoint Online site using PNP.
I did this previously using code:

$url = 'https://companygroup.sharepoint.com/sites/TeamBlockPolicy'
Connect-pnponline $url -useweblogin
$context = Get-PnPContext
$site = Get-PnPTenantSite -Url $url
$site.ConditionalAccessPolicy = [Microsoft.Online.SharePoint.TenantManagement.SPOConditionalAccessPolicyType]::BlockAccess
$site.Update()
Invoke-PnPQuery

Code above used to work in August, but not working anymore. When I call $site.Update() I get error:
'Method invocation failed because [PnP.PowerShell.Commands.Model.SPOSite] does not contain a method named 'Update'.'
Command "$site | gm" does not show method 'Update'

PNP version: SharePointPnPPowerShellOnline 3.29.2101.0
PowerShell version: 5.1

Hi @TSERKOVNYUK, Oleg ,

I tested the script with the new version "PnP.PowerShell" and old "SharePointPnPPowerShellOnline 3.29.2101.0" installed in local, the script will throw the same error (Only SharePointPnPPowerShellOnline 3.29.2101.0" installed won't throw the error):

For this issue, I suggest you can verify if the new PnP.PowerShell installed in your local using this command:

Get-Module -Name PnP.PowerShell -ListAvailable   

If it listed the version details like this, this mean the "PnP.PowerShell" installed:

Then the error is because of new version "PnP.PowerShell" has removed Update function for [PnP.PowerShell.Commands.Model.SPOSite] .

A solution is specify which module to use using Import-Module:

Import-Module -Name SharePointPnPPowerShellOnline  
  
$url = 'https://companygroup.sharepoint.com/sites/TeamBlockPolicy'  
Connect-pnponline $url -useweblogin  
$context = Get-PnPContext  
$site = Get-PnPTenantSite -Url $url  
$site.ConditionalAccessPolicy = [Microsoft.Online.SharePoint.TenantManagement.SPOConditionalAccessPolicyType]::BlockAccess  
$site.Update()  
Invoke-PnPQuery  

The error message will gone:

Thanks
Best Regards

Answer 2

Set-PnpTenantSite -Identity $siteUrl -DenyAddAndCustomizePages:$false

This works. :) Im using PnP.Powershell 1.9.0 in Visual Studio Code right now.

Answer 3

Thank you for solution. That resolved my problem. Interesting how the same result should be achieved in new version of PNP, because SharePointPnPPowerShellOnline is legacy.
