[BUG] Get-PnPTenantSite Returns Empty SensitivityLabel and Get-PnPProperty Fails Due to ClientObject Type Mismatch

[YuriySamorodov]

Reporting an Issue or Missing Feature

This is a bug report regarding the retrieval of SensitivityLabel values using Get-PnPTenantSite and the compatibility of objects with Get-PnPProperty. The SensitivityLabel information is not being populated as expected, and Get-PnPProperty fails to load the property from returned site objects.

Expected behavior

When running the following commands:

$sites = Get-PnPTenantSite
foreach ($site in $sites) {
    Get-PnPProperty -ClientObject $site -Property SensitivityLabel
}

or accessing:

$sites[100].SensitivityLabel

Expected result:
The SensitivityLabel property should return the sensitivity label assigned to each SharePoint site, as visible in the SharePoint Admin Center.
Get-PnPProperty should successfully populate/load the SensitivityLabel property for each site.

Actual behavior

• The SensitivityLabel property on the objects returned by Get-PnPTenantSite (with or without -Detailed) is always empty, even though sites have labels assigned.
• Attempting to use Get-PnPProperty -ClientObject $site -Property SensitivityLabel fails with this error:

  Get-PnPProperty: Cannot bind parameter 'ClientObject'. Cannot convert the "PnP.PowerShell.Commands.Model.SPOSite" value of type "PnP.PowerShell.Commands.Model.SPOSite" to type "Microsoft.SharePoint.Client.ClientObject".
  

• This indicates an object type mismatch: the SPOSite object returned is not compatible with the required ClientObject parameter for Get-PnPProperty.

Screenshots

• Attempting to use Get-PnPProperty produces the above error (see attached screenshot).

• Accessing $sites[100].SensitivityLabel always displays an empty value, even for labeled sites (see attached screenshot).

Steps to reproduce behavior

1. Use PnP PowerShell v3.1.141 to connect to SharePoint Online as a tenant administrator.

2. Run:

   $sites = Get-PnPTenantSite -Detailed
   foreach ($site in $sites) {
       Get-PnPProperty -ClientObject $site -Property SensitivityLabel
   }

   OR

   $sites = Get-PnPTenantSite -Detailed
   $sites.SensitivityLabel

3. Observe that the SensitivityLabel property is always empty, and that Get-PnPProperty fails due to a type incompatibility.

This seems to be the same behavior with Microsoft.Online.SharePoint.PowerShell :

It works when retrieving data for a single site:

which is the same behavior with Get-PnPTenantSite:

The same behavior occurs with the StorageQuotaType property. Both GetSPO-Site and Get-PnPTenantSite return an empty property unless the identity property is used.

Hey @YuriySamorodov , as mentioned in above comments, it is default behavior of CSOM SDK, you need to specify the identity parameter else it will be empty. Nothing we can do about it.
