[BUG] Set-PnPListItem -Batch and -ContentType do not seem to be compatible

[CraigChamberlain]

With Version 2.2.0 and 2.3.0 on Windows

When performing a command such as this:

$FolderWithSet = Get-PnPContentType  | Where-Object {$_.Name -eq "Specific Type"}
Set-PnPListItem -Batch $Batch -List "SomeList" -Identity 11 -Values @{"Text1"="SomeText"} -ContentType $FolderWithSet

I get the following error:

ErrorRecord    : Object reference not set to an instance of an object.
TargetSite     : Void ProcessRecord()
Message        : Object reference not set to an instance of an object.
Data           : {}
InnerException :

                    at System.Management.Automation.CommandProcessor.ProcessRecord()

If I do either of the following then It works fine.

Set-PnPListItem -List "SomeList" -Identity 11 -Values @{"Text1"="SomeText"} -ContentType $FolderWithSet
Set-PnPListItem -Batch $Batch -List "SomeList" -Identity 11 -Values @{"Text1"="SomeText"}
