[BUG] ConvertTo-PnPPage not copying metadata

[sonyam3]

Reporting an Issue or Missing Feature

Hi all. I'm using Visual Studio Code to convert wiki pages to modern site pages and retain the metadata, but it's failing to copy the metadata. It will successfully convert the page and include the created/modified info, but the metadata fields are blank in the pages it creates in SitePages. I ran the script before and after manually creating the columns in SitePages with the same results. I also ran this on 2 different wiki libraries in the same site collection with the same results. I ended up having to manually gather the metadata from the source wiki library and write it to the converted page in SitePages using the Set-PnPListItem command, so the source fields are accessible and the target fields are writable. I left that set command in the code below to show the workaround.

Columns in the source wiki library are as follows:

Wiki Content | Multiple lines of text |  
A Text Column | Single line of text |  
A Choice Column | Choice |  
Date Time Column | Date and Time |  
My Peeps | Person or Group |  
Number Column of Goodness | Number |  
Toggle Y/N | Yes/No |  
Created | Date and Time |  
Modified | Date and Time |  
Created By | Person or Group |  
Modified By | Person or Group |  
Checked Out To | Person or Group

Expected behavior

Please describe what output you expect to see from the PnP PowerShell Cmdlets

I expected the metadata from pages in the source wiki library to be written to the corresponding columns in the folder the ConvertTo-PnPPage commandlet creates in SitePages.

Actual behavior

Please describe what you see instead. Please provide samples of output or screenshots.

The wiki pages are converted to modern and the created/modified info is correct on the converted pages, but the metadata is not written so the fields on the target pages are blank.

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

get-module -Name "PnP.PowerShell" returns:

Manifest 2.2.0 PnP.PowerShell {Add-PnPAlert, Add-PnPApp, Add-PnPApplicationCustomizer, Add-PnPAvailableSiteClassification…}

Get-Module -Name "PnP.PowerShell" -ListAvailable returns:

Directory: C:\Users<my account>\OneDrive
Manifest 2.2.0 PnP.PowerShell Desk {Add-PnPAdaptiveScopeProperty, Add-PnPPropertyBagValue, Add-PnPSiteClassification, Copy-PnPFolder…}
Manifest 2.1.1 PnP.PowerShell Desk {Add-PnPAdaptiveScopeProperty, Add-PnPPropertyBagValue, Add-PnPSiteClassification, Copy-PnPFolder…}

Directory: C:\Program Files\WindowsPowerShell\Modules
Manifest 1.12.0 PnP.PowerShell Core,Desk {Add-PnPAdaptiveScopeProperty, Add-PnPPropertyBagValue, Add-PnPSiteClassification, Copy-PnPFolder…}
