Regenerate the Sitemap on a Local XM Cloud Docker Development Environment

Sitemap is Empty in a Local XM Cloud Development Environment

In a local XM Cloud Docker development environment, the /sitemap.xml front-end route always returns an empty XML file.

When a headless site is created, the sitemap media library item that is scaffolded is empty and has a size of 0 bytes.

This makes it impossible to debug the \src\pages\api\sitemap.ts API route handler and modify it to our needs.

This article dives into the sitemap regeneration process and solutions for local XM Cloud Docker development environments.

Impossible to Regenerate the Sitemap

In a hosted XM Cloud environment, this sitemap item is regenerated at the end of a publish operation of any item. An OnPublishEnd processor checks the SXA sites sitemap settings and regenerates the sitemap if enough time has elapsed since the last regeneration.

In a local Docker development environment, we cannot publish as we do not have a web database or a valid Experience Edge target. Attempting to publish results in an exception:

#Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
---> Sitecore.ExperienceEdge.Connector.ContentHubDelivery.Exceptions.EdgeApiException: [ExperienceEdge Publishing]: An error has occurred while publishing JobStart event 9614b999-f4dc-4fb7-ab08-75bf8a2bf429 for publishing job '638580401015070000'. Please see inner exception for more details.
---> Sitecore.Exceptions.ConfigurationException: Invalid Authority connection string. Required parameter 'url' is missing.

Thus, the sitemap is never regenerated and the media library item is never updated.

Introducing the Sitecore XM Cloud Sitemap Developer Utilities

Faced with that limitation and the need to replicate a production sitemap issue in a development environment, I found creative ways to regenerate the sitemap media library item and get valuable information.

The end result is a configurable utility page that can be deployed to a local XM Cloud CM. There are a few steps to use it:

  1. Ensure your local XM Cloud Docker Compose project is running and the CM is healthy and accessible.

  2. Create a generateSitemap.aspx file in your project \docker\deploy\platform folder with the code below:

     <%@ Page language="c#" %>
 <%@ Import Namespace="Microsoft.Extensions.DependencyInjection" %>
 <%@ Import Namespace="Sitecore.Abstractions" %>
 <%@ Import Namespace="Sitecore.Configuration" %>
 <%@ Import Namespace="Sitecore.Data" %>
 <%@ Import Namespace="Sitecore.Data.Items" %>
 <%@ Import Namespace="Sitecore.DependencyInjection" %>
 <%@ Import Namespace="Sitecore.Events" %>
 <%@ Import Namespace="Sitecore.Globalization" %>
 <%@ Import Namespace="Sitecore.Pipelines" %>
 <%@ Import Namespace="Sitecore.Publishing" %>
 <%@ Import Namespace="Sitecore.Sites" %>
 <%@ Import Namespace="Sitecore.Web" %>
 <%@ Import Namespace="Sitecore.XA.Foundation.SiteMetadata.EventHandlers" %>
 <%@ Import Namespace="Sitecore.XA.Foundation.SiteMetadata.Sitemap" %>
 <%@ Import Namespace="Sitecore.XA.Foundation.SiteMetadata.Pipelines.Sitemap.GenerateSitemapJob" %>

 <script runat="server">
     // IMPORTANT
     // Change the values of those variables to match the Headless SXA site name and home item you want to generate the sitemap for.
     private const string SITE_NAME = "sxastarter";
     private const string HOME_ITEM_ID = "{BEE17B56-2406-4935-A730-CFE90356BE2C}";
 </script>

     }
 </script>

  3. The first <script> block contains 2 variables you must set to the site name and site home item ID you want the sitemap to be generated for. Ensure you set those correctly.

     <script runat="server">
     // IMPORTANT
     // Change the values of those variables to match the Headless SXA site name and home item you want to generate the sitemap for.
     private const string SITE_NAME = "sxastarter";
     private const string HOME_ITEM_ID = "{BEE17B56-2406-4935-A730-CFE90356BE2C}";
 </script>

  4. Save the file. The container entrypoint script will copy the saved file to the CM container wwwroot folder.

  5. In your browser, load the https://xmcloudcm.localhost/generateSitemap.aspx page and follow the instructions.

    Sitecore XM Cloud sitemap developer tools interface with cache and sitemap generation options.

  6. Reload your sitemap route and enjoy a regenerated sitemap!

Tips When the Sitemap Does Not Generate

  1. Ensure you edited the SITE_NAME and HOME_ITEM_ID variables values in the generateSitemap.aspx file and you saved your changes.
  2. Check the site’s sitemap settings (/sitecore/content/YourSiteCollection/YourSite/Settings/Sitemap)
    1. Crawler: The value should be either itemCrawler or indexCrawler
      1. Those crawlers are defined the Sitecore config under the <sitemapItemCrawler> node.
    2. Cache
      1. Refresh threshold: Set it to 0 to force a regeneration every time.
      2. Cache Type: You can play with the “Stored in cache” and “Stored in file” options.
        1. Both should update the sitemap media library item.
      3. Cache expiration: Set it to 0 to force a regeneration every time.
    3. Media items
      1. Generate sitemap media items: Ensure it is checked.
  3. Delete your site sitemap media library item (/sitecore/media library/Project/YourSiteCollection/YourSite/Sitemaps/YourSite/sitemap).
    1. Sitecore will inform you that there are links to that element. Chose to remove the links.
    2. The sitemap media library item will be recreated and relinked correctly the next time it will be generated.

Happy Sitecoring!
