Issue after migrating a project developed on Kentico13 to Xperience. Unable to use the Page Builder

2025/05/14 7:50 AM

I encountered an issue after migrating a project developed on Kentico 13 to Xperience. I am unable to use the Page Builder and encountered the following error

An unhandled exception occurred while processing the request.

InvalidOperationException: The view on path '' could not be found and there is no page template registered for selected page.

Kentico.Content.Web.Mvc.Routing.Internal.KenticoPageBuilderWebPageController.Index()

This is my migration configuration.

This is the view part of the Home page, which I noticed was not included in the migration to Xperience. (KenticoPlayground_Home.cshtml)

@addTagHelper *, Kentico.Content.Web.Mvc

@model Kentico.Content.Web.Mvc.Routing.IPageViewModel<CMS.DocumentEngine.Types.KenticoPlayground.Home>

@{
    ViewBag.Title = Model.Page.DocumentName;
}

@section styles
{
@* Includes CSS necessary for page builder functionality *@
        <page-builder-styles />
}
@section scripts
{
@* Includes scripts necessary for page builder functionality *@
        <page-builder-scripts />
}

<div class="container-fluid">
    <section class="teaser">
            @* <p>@Model.Page.Fields.Title</p> *@
        <div class="clearfix"></div>
    </section>
    <section class="content">

First, I would recommend raising your issue in the Xperience by Kentico: Kentico Migration Tool repository - it will get direct support there. If you want to link to your issue here on the Q&A discussions, that's ok.

Second, to identify the cause of your issue you'll want to query your Xperience by Kentico database and look at the ContentItemCommonDataVisualBuilderWidgets and ContentItemCommonDataVisualBuilderTemplateConfiguration columns of the CMS_ContentItemCommonData for the content item you are interested in (for example, your home page).

Here's the query I'd run for the Kentico Community Portal project.

SELECT CI.ContentItemName
    , CD.ContentItemCommonDataVisualBuilderWidgets
    , CD.ContentItemCommonDataVisualBuilderTemplateConfiguration
FROM CMS_ContentItemCommonData CD
INNER JOIN CMS_ContentItem CI
    ON CI.ContentItemID = CD.ContentItemCommonDataContentItemID
INNER JOIN KenticoCommunity_HomePage HP
    ON HP.ContentItemDataCommonDataID = CD.ContentItemCommonDataID

If there is nothing in these columns then your page is not configured to use Page Templates. Take a look at this blog post for more tips on resolving Page Template issues.

My guess is your content tree routing is not correctly configured - so take a look at those docs.

A few additional notes...

Your sample code looks like it's Kentico Xperience 13 code - some of that won't work in Xperience by Kentico. You should read the Xperience by Kentico getting started tutorial before trying to perform an upgrade.

We have an entire architecture and step-by-step upgraded guide for developers moving from Kentico Xperience 13 to Xperience by Kentico. Please review that guide to help give you some perspective on this upgrade process.
