In Sitecore XM Cloud, sharing a site across multiple headless tenants isn't supported out-of-the-box due to the isolated nature of tenants. However, there are a few alternatives depending on your specific requirements:

Key Points

1. SXA Shared Site:

   • SXA’s Shared Site feature allows sharing of presentation and data sources within a single tenant.
   • It does not support sharing across tenants by design, as tenants are meant to be isolated.

2. Restructuring the Tenant/Site Setup:

   • If sharing site content across brands is essential, consider restructuring your tenant and site setup to group related sites under a single tenant.
   • Example:
     • Tenant (Brand):
       • Site 1 (Microsoft)
       • Site 2 (Apple)

3. Item Cloning:

   • For specific content sharing, you can use the item cloning feature to replicate content across sites within a tenant.
   • This approach works well for small-scale content sharing.

4. Role-Based Access:

   • Within a single tenant, you can create shared folders/sites and assign specific roles to users for access control.

Proposed Structure Example

• Tenant A (Shared Site X):

  • Site 1
  • Site 2
  • Shared Site X

• Tenant B (Shared Sites X and Y):

  • Site 3
  • Site 4
  • Shared Site Y

• Tenant C (Shared Sites X, Y, and Z):

  • Site 5
  • Site 6
  • Shared Site Z

Recommendations

• If restructuring tenants isn’t feasible, use item cloning or shared folders within a single tenant.
• For better long-term scalability and fewer manual steps, align the tenant/site structure with the requirements for content sharing at the planning stage.
• If sharing is minimal, item cloning may suffice without extensive rework.

This approach should help address your team’s need for shared sites across brands while adhering to Sitecore XM Cloud’s design principles.

Sitecore XM Cloud: Custom Error Details in Content Editor (YSOD)

Sometimes, when using the Sitecore XM Cloud Content Editor, you might encounter the Yellow Screen of Death (YSOD). This raises a common question: Can we enable custom error details to see more information about these errors?

The answer lies in modifying the web.config file. In XM Cloud, while you can adjust settings using XDT transformations, Sitecore doesn’t provide a direct option to enable custom error details specifically for the Content Editor.

To make changes:

1. Check out the Sitecore documentation on XM Cloud build configuration.
2. Use XDT transformations to adjust the relevant settings in the web.config file for your instance.

This should allow you to customize error handling and potentially show more details during troubleshooting.

Step-by-Step Approach to Enabling Custom Error Details

1. Understand XM Cloud Deployment Model:
   Sitecore XM Cloud is a containerized environment, and configuration changes are handled through XDT transformations applied during the build process. You cannot directly edit the web.config in the deployed environment, but you can apply transformations during deployment.

2. Modify web.config Settings:
   To display detailed error information, update the web.config settings using an XDT transformation to include custom error configurations.

   Here’s an example of an XDT transformation snippet you can use:

   
   <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
     <system.web>
       <customErrors mode="Off" xdt:Transform="SetAttributes" xdt:Locator="Match(mode)" />
     </system.web>
     <system.webServer>
       <httpErrors errorMode="Detailed" xdt:Transform="SetAttributes" xdt:Locator="Match(errorMode)" />
     </system.webServer>
   </configuration>
   

   • customErrors mode="Off": Disables custom error pages and displays detailed ASP.NET errors.
   • httpErrors errorMode="Detailed": Configures the IIS server to display detailed error messages.

3. Apply XDT Transformations in Your Build Configuration:

   • Ensure the above transformation file (e.g., web.release.config) is included in your project.
   • During deployment, Sitecore XM Cloud will apply this transformation to the web.config.

4. Check Sitecore Documentation:
   Refer to the official Sitecore XM Cloud documentation on build configuration for guidelines on applying and validating XDT transformations in XM Cloud deployments.

5. Deploy and Test:

   • Deploy the updated configuration to your XM Cloud instance.
   • Trigger the error in the Content Editor to confirm that detailed error messages are now displayed.

Best Practices and Considerations

• Security Awareness:
  Only enable detailed error messages in non-production environments. Exposing detailed errors in a production environment can reveal sensitive information and pose security risks.

• Log Monitoring:
  Use Sitecore’s logging mechanisms and external monitoring tools (such as Application Insights) to collect and analyze error data without displaying it directly in the Content Editor.

• Rollback Strategy:
  Ensure you have a rollback plan in case the configuration changes cause unintended behavior.

Conclusion

While Sitecore XM Cloud does not offer a direct option to enable custom error details for the Content Editor, leveraging XDT transformations to modify the web.config file provides a powerful way to manage error handling. By applying these changes responsibly, you can streamline troubleshooting and improve the development experience.

GraphQL Not Working for "Load More" Functionality on Published Environment

Issue: GraphQL Not Working for "Load More" Functionality on Published Environment

Summary:
The "Load More" functionality using GraphQL queries works correctly in preview mode and local environments but fails on the published GraphQL endpoint. The error message indicates an execution issue with the children query, specifically with the endCursor value.

Root Cause:

1. Incorrect Context ID: The published environment may be using the Preview Context ID instead of the Live Context ID in the configuration.
2. Unpublished Items: Items referenced in the query might not be published or available in the Live Experience Edge.
3. Incorrect Cursor Value: The endCursor value may not be valid for the published environment, potentially copied from the Preview environment.

Solution:

1. Update Context ID:

   • Set the correct SITECORE_EDGE_CONTEXT_ID for the Live environment in your hosting provider's environment variables (e.g., Vercel).
   • Redeploy the application to ensure the correct configuration.

2. Verify Published Items:

   • Confirm that all required items are published and available in the Live Edge endpoint.

3. Use Correct Cursor:

   • Run the initial query (children (first: 4)) without the after parameter on the Live endpoint to retrieve the correct endCursor value.
   • Use the returned endCursor for subsequent queries.

4. Test Queries in Published Environment:

   • Verify the GraphQL query directly in the published GraphQL IDE to ensure the configuration works correctly.

By following these steps, the "Load More" functionality should work as expected in the published environment.

Content Serialization Challenges in Sitecore XM Cloud

We encountered a recurring issue with content serialization in Sitecore XM Cloud, particularly when dealing with presentation updates like page branches and component renderings. Below is a summary of the problem, possible causes, and steps to replicate the issue.

Issue Description

• Content changes, such as updates to page branches or component renderings, are serialized into .yml files and deployed to XM Cloud.
• On the initial deployment, the updates reflect correctly in XM Cloud.
• However, after subsequent deployments (even with unrelated changes), the previously deployed content reverts to its earlier state.
• This behavior is observed only for certain renderings and not universally.

Suspected Cause

This behavior appears related to the interaction between:

1. IAR (Items as Resources): Serialized content deployed as IAR files in XM Cloud.
2. SQL Database in XM Cloud CM: Changes made directly in XM Cloud CM's content editor are stored in its SQL database, superseding IAR content.
3. Deployment Overrides: Subsequent deployments fail to update content because the local serialized content doesn't reflect changes made in the XM Cloud CM.

Steps to Replicate

1. Create a New Site:

   • Navigate to Presentation > Page Branches.
   • Create a new page branch template and add a component with rendering.
   • Update the component's data source and modify a value.

2. Deploy Changes:

   • Serialize and deploy the changes to XM Cloud. Confirm that the changes are reflected.

3. Perform Subsequent Deployment:

   • Make additional changes unrelated to the previous deployment.
   • Deploy again and observe that the earlier updates to the page branch or rendering have reverted.

Proposed Solutions

1. Manual Cleanup:

   • Use the dotnet sitecore itemres cleanup --force command to remove outdated content in XM Cloud CM before deploying new serialized content.

2. Synchronization:

   • Before deploying new serialized content, pull the latest content changes from XM Cloud CM to the local environment to ensure alignment between local and XM Cloud states.

3. Direct Content Management:

   • If frequent authoring occurs in XM Cloud CM, coordinate deployments to minimize conflicts between serialized content and database-stored updates.

Best Practices

• Track Content Changes: Maintain clear documentation of changes made in XM Cloud CM to prevent inadvertent overrides during deployments.
• Test Locally: Validate serialized content thoroughly in local environments before deploying.
• Streamline Collaboration: Establish workflows that synchronize content updates between developers and content authors effectively.

This approach should help mitigate inconsistencies in content serialization and deployment within Sitecore XM Cloud environments.

Resolving Facet Functionality Issues in Search Integration with Sitecore XM Cloud

During the integration of the Search application with Sitecore XM Cloud, we encountered an issue where facets functionality was not working as expected. While search results displayed correctly, the facets' checkboxes were unresponsive, and an error appeared in the console when attempting to interact with them.

Here’s a detailed breakdown of the problem and the steps taken to resolve it.

Issue Overview

• Symptoms:
  • Facet checkboxes were displayed but were unresponsive to clicks.
  • Console error: Cannot read properties of undefined (reading 'facets').
• Environment:
  • Frontend: Next.js application.
  • API Endpoint: Sitecore Discover API.
• Observation:
  • The facets functionality worked perfectly during a proof of concept (POC) outside the XM Cloud environment with the same API and codebase.

Investigation

1. Code Review:

   • The issue was identified in the SearchResultWidget.tsx component, particularly in the onFacetValueClick function.
   • An arrow function (onFacetValueClick={() => onFacetClick}) was used instead of directly passing the callback function.

2. Environment Consistency:

   • Verified that the API response was identical in both environments (POC and XM Cloud).
   • Compared configurations and ensured the same codebase was deployed.

3. Styled vs. CSS Components:

   • The demo site used styled components, whereas the integrated application used .css files. An attempt was made to replicate the behavior using styled components for troubleshooting.

Solution

1. Fixing the Facet Click Logic:

   • Replaced the arrow function with a direct callback function.

   
   
   <SearchResultsAccordionFacets
       defaultFacetTypesExpandedList={[]}
       onFacetValueClick={onFacetClick}
       className="sitecore-accordion-facets-root"
   />
   

2. Testing and Validation:

   • Updated the @sitecore-search/react package to version 2.2.3, resolving known bugs in earlier versions (2.1.1).
   • Validated the changes locally and deployed them to the XM Cloud environment.

3. Facet Behavior in URL:

   • For modifying the facet behavior in the URL (displaying facet value instead of ID), implemented the useSearchResultsSelectedFacets hook from the Search SDK.

Key Findings

• The issue originated from a combination of incorrect function usage and a known bug in the older version of the @sitecore-search/react package.
• XM Cloud-specific configurations did not impact the functionality; the error was resolved by addressing code-level issues and updating dependencies.

Conclusion

By fixing the callback logic and updating the relevant package, the facets functionality was restored. This experience highlighted the importance of:

1. Keeping dependencies up to date.
2. Ensuring code consistency across environments.
3. Validating functionality with minimal, reproducible examples.

If you encounter a similar issue, check your package versions, verify API responses, and thoroughly review component implementations. The above steps should help resolve most facet-related issues during Sitecore Search integrations.

Option to Rollback Deployments in Sitecore XM Cloud

During a recent discussion with the Sitecore Support Team, we confirmed that XM Cloud does not offer a built-in rollback mechanism for deployments. However, since XM Cloud projects are typically hosted on version control platforms like GitHub, reverting changes can be managed effectively through version control processes.

uring a recent discussion with the Sitecore Support Team, we confirmed that XM Cloud does not offer a built-in rollback mechanism for deployments. However, since XM Cloud projects are typically hosted on version control platforms like GitHub, reverting changes can be managed effectively through version control processes.

Here’s a professional approach to handling rollbacks in XM Cloud using a Windows environment:

Step-by-Step Rollback Process

1. Revert Changes in Version Control

1. Navigate to Your GitHub Repository (or any equivalent version control platform).
2. Identify the Commit to Revert To:
   • Go to the Commit History of your repository.
   • Locate the last known stable commit before the problematic deployment.
3. Revert the Commit:
   • On GitHub, click on the commit you want to revert.
   • Select the “Revert” option. This will create a new commit that undoes the changes introduced by the problematic deployment.
4. Commit the Reverted Changes:
   • Confirm and commit the changes to your repository.

2. Link to a Stable Branch

1. Create a New Branch for the Reverted Changes:
   • In GitHub, navigate to the repository’s Branches tab.
   • Create a new branch based on the reverted changes, e.g., stable-rollback.
2. Update the Environment Configuration:
   • In your XM Cloud deployment settings, update the environment to use the new stable branch.

3. Rebuild and Redeploy

1. Trigger the "Build & Deploy" Action in XM Cloud:
   • Go to the XM Cloud interface or your CI/CD pipeline.
   • Select the new stable branch and initiate the “Build & Deploy” action.
2. Verify the Deployment:
   • Ensure the deployment completes successfully.
   • Validate that the site functions as expected, and all services are operational.

Benefits of This Approach

• Efficiency: Quickly revert to a stable state without extensive troubleshooting.
• Control: Maintain full transparency over code changes and deployments.
• Flexibility: Easily manage multiple stable branches for different environments.
• Version History: Maintain a clear audit trail of changes and rollbacks for future reference.

By leveraging version control processes, you can effectively manage rollbacks in Sitecore XM Cloud and ensure a smooth deployment experience.

Resolving Multiple HTTPS Entries in Sitemap

Issue Observed:

During a recent project, I observed that multiple HTTPS entries were being generated in the sitemap. This issue not only caused redundancy but also had potential implications for SEO and website performance.

After a detailed investigation, I determined that the problem was related to incorrect configuration settings within Sitecore.

Root Cause Analysis

In Sitecore, the configuration for each site defines how URLs are generated, including protocol and host information. The issue was traced to the following path:

/sitecore/content/Site/Settings/Site Grouping/Site1

Within this configuration, the Target Hostname field included the HTTPS protocol, which resulted in duplicate entries being created in the sitemap.

For example:

https://www.example.com

When the sitemap was generated, this setting caused the URLs to be prefixed incorrectly, leading to multiple instances of HTTPS URLs appearing.

Solution

The fix for this issue was straightforward and involved modifying the Target Hostname setting. Here’s how it was resolved:

1. Navigate to the Site Settings:

   • Go to: /sitecore/content/Site/Settings/Site Grouping/Site1

2. Correct the Target Hostname:

   • Remove the HTTPS prefix from the Target Hostname field.
   • Instead of: https://www.example.com
   • Use: www.example.com

3. Save and Publish the changes to ensure they take effect.

Why This Fix Works

Sitecore generates URLs dynamically based on the Target Hostname configuration. By including the protocol (https://) directly in the Target Hostname field, Sitecore was misinterpreting the setting and creating redundant HTTPS entries.

By specifying only the hostname (www.example.com), Sitecore uses the appropriate protocol based on other configurations, ensuring consistent and accurate URL generation in the sitemap.

Results

After implementing this change:

• The sitemap no longer displayed duplicate HTTPS entries.
• URL generation was consistent and aligned with best practices for SEO.
• The overall sitemap was clean, accurate, and free of redundancy.

Key Takeaways

• Check Hostname Settings: Always ensure the Target Hostname field contains only the hostname, without protocol prefixes.
• Follow Best Practices: Let Sitecore handle protocol resolution based on your site's configurations for HTTP and HTTPS.
• Regular Sitemap Audits: Periodically review your sitemap to identify and address any anomalies that may impact SEO.

By maintaining proper settings in Sitecore, you can avoid sitemap issues and ensure a seamless experience for both search engines and users.
