    We did a test upgrade to 4.4 in an OOB 4.1 environment and after the upgrade we only get a blank page when we login to the main page. UX apps and the admin console load fine, and we can access individual records if we go to them directly via a link. The Developer Tools show we are getting a 500 response from [TRIRIGA url]/api/v1/session/status when we login to access the front end. The console shows the following errors:

    Failed to load resource: the server responded with a status of 500 (Internal Server Error)     :9443/api/v1/session/status:1

    TypeError: Cannot read properties of null (reading 'length')          react-dom.production.min.js:209

    Uncaught (in promise) TypeError: Cannot read properties of null (reading 'length')   SessionExpired.js:21

    Has anyone else encountered these issues or successfully upgraded to 4.4? We are using Oracle DB and Liberty.


    Update: The following server.xml setting was accidentally set to 3.0 instead of 3.1

    <feature>servlet-3.1</feature>
