[BUG] Restore-PnPRecycleBinItem - Type Conversion Errors

[YuriySamorodov]

Reporting an Issue or Missing Feature

I'm reporting an issue with the Restore-PnPRecycleBinItem cmdlet which appears to have a type conversion problem that makes it impossible to restore items from the recycle bin.

Expected behavior

When using Restore-PnPRecycleBinItem with an Identity parameter (either directly or piped from Get-PnPRecycleBinItem), the cmdlet should successfully restore the item to its original location as shown in the help examples.

Actual behavior

The cmdlet fails with type conversion errors regardless of how the Identity is provided:

1. When using direct ID:

Restore-PnPRecycleBinItem -Identity $torestore.Id
Restore-PnPRecycleBinItem: Cannot bind parameter 'Identity'. Cannot convert the "12617497-069e-4fe3-a032-39b5f3956406" value of type "System.Guid" to type "PnP.PowerShell.Commands.Base.PipeBind.RecycleBinItemPipeBind".

2. When piping from Get-PnPRecycleBinItem:

Get-PnPRecycleBinItem -Identity $torestore.Id | Restore-PnPRecycleBinItem
Get-PnPRecycleBinItem: Cannot bind parameter 'Identity'. Cannot convert the "Microsoft.SharePoint.Client.RecycleBinItem" value of type "Microsoft.SharePoint.Client.RecycleBinItem" to type "System.Guid".

3. Even when trying to pipe the entire command:

Restore-PnPRecycleBinItem -Identity ( Get-PnPRecycleBinItem -Identity $torestore.Id )
Restore-PnPRecycleBinItem: Object reference not set to an instance of an object.

Steps to reproduce behavior

1. Connect to a SharePoint site using Connect-PnPSite
2. Get a recycle bin item using Get-PnPRecycleBinItem
3. Try to restore it using any of the following methods:

$item = Get-PnPRecycleBinItem
Restore-PnPRecycleBinItem -Identity $item.Id
# or
$item | Restore-PnPRecycleBinItem
# or
Restore-PnPRecycleBinItem -Identity $item

What is the version of the Cmdlet module you are running?

Please include the output of Get-Module -Name "PnP.PowerShell" -ListAvailable

PnP.PowerShell 2.99.96

Which operating system/environment are you running PnP PowerShell on?

Based on the command prompt shown in the screenshots, this is being run on Windows.
