Get-PnPWikiPageContent error

Hi

When I execute the following I get an error:

Connect-PnPOnline -Url https://<tenant>.sharepoint.com/sites/entwiki -Credentials (Get-Credential)

$p = Get-PnPWikiPageContent -ServerRelativePageUrl '/sites/entwiki/Pages/home.aspx'

Error:

Get-PnPWikiPageContent : The property or field has not been initialized. It has not been requested or the request has not been executed. It 
may need to be explicitly requested.

The following works, this confirms the file is available:

$f = Get-PnPFile -ServerRelativeUrl '/sites/entwiki/Pages/home.aspx' -AsListItem

Am I doing something wrong, or is this a bug?

Thanks.
