How to create Repost Page (Modern Page Library) with PowerShell

Dear all,

I tried to create a PowerShell script to create automatically "Modern Repost Page" pointing to the news page published into the SharePoint Publishing site (Global Intranet Site).

The manual creation from the "Modern News" webpart or "News" list page (https://[YourTenant].sharepoint.com/_layouts/15/news.aspx), I can also modify some metadata via the PowerShell code.

But I can't create correctly the Report Page via PowerShell, it's loaded with the current content type and the metadata are OK, but the News Webpart is not showing the automatically created Report Pages.

The current part of the code I created is inspired from what I found:

• https://docs.microsoft.com/en-us/sharepoint/dev/solution-guidance/modern-experience-customizations-customize-pages

// pagesLibrary is List object for the "site pages" library of the site
ListItem item = pagesLibrary.RootFolder.Files.AddTemplateFile(serverRelativePageName, TemplateFileType.ClientSidePage).ListItemAllFields;

// Make this page a "modern" page
item["ContentTypeId"] = "0x0101009D1CB255DA76424F860D91F20E6C4118";
item["Title"] = System.IO.Path.GetFileNameWithoutExtension("mypage.aspx");
item["ClientSideApplicationId"] = "b6917cb1-93a0-4b97-a84d-7cf49975d4ec";
item["PageLayoutType"] = "Article";
item["PromotedState"] = "0";
item["CanvasContent1"] = "<div></div>";
item["BannerImageUrl"] = "/_layouts/15/images/sitepagethumbnail.png";
item.Update();
clientContext.Load(item);
clientContext.ExecuteQuery();

My adapted version is:

			[string]$NewsPageFileName = "/SitePages/"+ $MyCSVPublishingDate.ToString("yyyyMMdd") +'-'+ $CSVItem.NewsURL.Substring($CSVItem.NewsURL.LastIndexOf("/") + 1)
			Write-Host "                >> $($MyPagelistItems.Count) PageList Item Found, Need to be created [ $NewsPageFileName ]" -ForegroundColor Red # TO CREATE !!!

			$NewPageitem = $MyPagelist.RootFolder.Files.AddTemplateFile($NewsPageFileName, [Microsoft.SharePoint.Client.TemplateFileType]::ClientSidePage).ListItemAllFields

			# Make this page a "modern" page
			$NewPageitem["ContentTypeId"] = "0x0101009D1CB255DA76424F860D91F20E6C4118002A50BFCFB7614729B56886FADA02339B00FB61AB42CC88E741A501DF164E1EDB74";
			$NewPageitem["Title"] = $CSVItem.NewsTitle
			$NewPageitem["ClientSideApplicationId"] = "b6917cb1-93a0-4b97-a84d-7cf49975d4ec"
			$NewPageitem["_OriginalSourceUrl"] =  $MyCSVNewsURL
			$NewPageitem["Editor"] = $MyEditoruserAccount.Id
			$NewPageitem["Author"] = $MyEditoruserAccount.Id
			$NewPageitem["Description"] = $MyCSVNewsDescription
			$NewPageitem["BannerImageUrl"] = $MyCSVNewsPictureURL;
			$NewPageitem["Modified"] = $MyCSVPublishingDate;
			$NewPageitem.Update();
			$MyctxTemp.Load($NewPageitem);
			$MyctxTemp.ExecuteQuery();

The result from the file list view:RepostPage

As you can see the bannerimage is loaded correctly, title also and description too, but when I click on the item to check and modify a value, I load the basic Empty SitePage and not the Repost Page.

Do you have any idea what I have to do to fix that ?

Thanks by advance.
