Intrexx Post-Update Issue and Resolution

After updating an Intrexx portal, some applications may fail to load properly and instead display error messages to users. Upon inspection of the application’s internal files, you may find that the directories are empty.

Quick Fix: Re-publishing the Application

In most cases, simply re-publishing the affected application resolves the issue and restores functionality.

• If the publish is successful, the application should work as expected.
• If the publish fails, and the log error contains <parameter3> is null” in it, then further steps are required.

Root Cause

This error is related to the Solr search engine, even if the portal itself is not actively using Solr. The problem occurs because a portal language entry is missing from Solr’s internal configuration after the update. You can verify this by navigating to: Portal Manager > Tools > Search > Solr Search Server Then, under Manage cores or collections, check which portal language is missing a thumbs-up indicator.

Resolution: Fixing the <parameter3> is null Error

1. Connect to the portal’s internal file system.
2. Locate the following file: /opt/intrexx/org/<portal_name>/internal/search/solr/templates/solrMapping.xml
3. Open the file and scroll to the bottom, where the list of portal languages is defined.
4. Add the missing language entry.
5. Save the file and re-publish the application.

Once the missing language is restored, the publish should complete successfully, and the application will function normally again.
