Get-PnPWebPart returns no results for modern SPO pages

[Dominic Horne]

Using PnP Powershell, Get-PnPWebPart returns no results. 

$webParts = Get-PnPWebPart -ServerRelativePageUrl "/sites/SampleSite/SitePages/ABC.aspx"

$webParts.Count = 0

ABC.aspx is a page in the Site Pages library within a modern team site.

Get-PnPFile successfully returns the page.
