Issue: Convert-ToPnPPage encounters critical errors during transformation of page when using the -Folder "<root>" parameter #671

Problem Area

[ x] Page Transformation: Error during the use of page transformation from PnP PowerShell [ ] Page Transformation: Error during the use of page transformation from .Net [ ] Page Transformation: Page is not looking correct after transformation [ ] Modernization Scanner: something went wrong...

Expected or Desired Behavior

We are attempting to transform a page when using a cross site transformation from an on-prem SharePoint 2016 site to a modern SharePoint Online communication site. The page exists in the root of the source site at /[SiteName]/default.aspx and is the site home page. We are using the cmdlet with the -Folder "" parameter. Our expected behaviour is that the page is transformed and copied to the target site 'Site Pages' library.

Observed Behavior

The operation is failing with a critical error and the error message states: "Site does not have a sitepages library and therefore this page can't be a client side page." The target site does however have a site pages library and using the cmdlet to copy publishing pages from the source site Pages library to the target site Site Pages library has been successful.
