Question

Hi,

I am unable to create a publishing page in any of the subsites,gettingerror:"the given key was not present in the dictionary". but able to create in site collection level.

 

Below is my Code:

 

$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($ParentSiteurl)

$ctx.Credentials = $credentials

$ctx.ExecuteQuery()

$subsiteCtx = New-Object Microsoft.SharePoint.Client.ClientContext($subsiteUrl)

$subsiteCtx.Credentials = $credentials

$subsiteCtx.ExecuteQuery()

$pageLayoutList = $ctx.Web.Lists.GetByTitle("Master Page Gallery")

$ctx.Load($pageLayoutList)

$ctx.ExecuteQuery()

$pageLayoutQuery = New-Object Microsoft.SharePoint.Client.CamlQuery

$pageLayoutQuery.ViewXml = "OneSmallOneLargeOneSmallColumnLayout.aspx"

$pageLayouts = $pageLayoutList.GetItems($pageLayoutQuery)

$ctx.Load($pageLayouts)

$ctx.ExecuteQuery()

 

$pageLayout = $pageLayouts[0]

#Get the publishing Web

$pubWeb = [Microsoft.SharePoint.Client.Publishing.PublishingWeb]::GetPublishingWeb($subsiteCtx, $subsiteCtx.Web)

$subsiteCtx.Load($pubWeb)

$subsiteCtx.ExecuteQuery()

$pageInfo = New-Object Microsoft.SharePoint.Client.Publishing.PublishingPageInformation

$pageInfo.Name = $pageName

$pageInfo.PageLayoutListItem =$pageLayout

$page =$pubWeb.AddPublishingPage($pageInfo)

$subsiteCtx.Load($page)

$subsiteCtx.ExecuteQuery()

$PagesList = $subsiteCtx.Web.Lists.GetByTitle("Pages")

$subsiteCtx.Load($PagesList)

$subsiteCtx.ExecuteQuery()

$publishPage = $subsiteCtx.Web.GetFileByServerRelativeUrl($PagesList.ParentWebUrl + "/Pages/" + $pageName)

$subsiteCtx.Load($publishPage)

$subsiteCtx.ExecuteQuery()

$publishPage.CheckIn("Page Created", [Microsoft.SharePoint.Client.CheckinType]::MajorCheckIn)

$publishPage.publish("Publish")

$subsiteCtx.load($publishPage)

$subsiteCtx.ExecuteQuery()
