Add-PnPFile -Path "test1.csv" -Folder "Shared Documents/"I have a PnP PowerShell Cmdlets (2.99.142) version.
Could it be that you are using a ClientSecret to connect using Connect-PnPOnline and that ACS has been disabled on this tenant? I've seen this vague error getting thrown in that scenario. I've pushed a PR to PnP Framework to make this error at least a little less vague.
Use:Get-PnPTenant | Select DisableCustomAppAuthentication
To check if ACS is disabled on your tenant. It should report back False. If it reports back True, use Set-PnPTenant -DisableCustomAppAuthentication:$false to enable it or better yet, stop using ClientSecrets, start using certificates :)
Hello,
I am encountering the same issue in my tenant using Get-PnPSiteTemplate:
The command line I use is:
$ctxSp = Connect-PnPOnline -url "https://m365mystic.sharepoint.com/sites/CTypeTest-Manual" -ClientId $appId -Tenant $tenantId -Thumbprint $certThumbprint -ReturnConnection
Get-PnPSiteTemplate -Out template2.xml -Connection $ctxSp -IncludeAllPages
Get-PnPSiteTemplate: Value cannot be null. (Parameter 'source')As you can see the connection is created without error so the appID/certificate info used to connect, but when I run Get-PnPSiteTemplate it throws the error. There is no '-Source' parameter for this cmdlet per the documentation.
The interesting thing is, in another tenant where I tried this, it works fine. Both tenants have "DisableCustomAppAuthentication:False".
Do you know if there is some more recent change rolling out to tenants currently that might cause this failure in all tenants in the future (not including the switch away from the App Model that will require "DisableCustomAppAuthentication :True" come April 2026?
Thanks

TimeStampUtc : 10/04/2025 13:26:48DisableCustomAppAuthentication is set to false (we are using another app that requires this for now). I connect using:
$ctxSp = Connect-PnPOnline -url "https://m365mystic.sharepoint.com/sites/CTypeTest-Manual" -ClientId $appId -Tenant $tenantId -Thumbprint $certThumbprint -ReturnConnection
which leverages an app registration in the tenant (hence $appId ) and a certificate to connect.
I'm also having this problem with Get-PnPSiteTemplate on delegated permission/login
Connect-PnPOnline -Url "https://contoso.sharepoint.com/sites/sitename" -ClientID "<app_registration_id>" -Interactive Get-PnPSiteTemplate -Out "template.xml"For what it's worth in the powershell output I can see it going through:
"extracting Template from https://contoso.sharepoint.com/site. [Regional Settings ]
"extracting Template from https://contoso.sharepoint.com/site. [Supported UI Languages ]
"extracting Template from https://contoso.sharepoint.com/site. [Audit Settings ]
"extracting Template from https://contoso.sharepoint.com/site. [Site Security ]and it seems to fail after that.
