Hi, We want to get started on our constellation journey. We want to develop a new landing page, so thought this was a good usecase to get started with hybrid UI. Was thinking to leverage constellation for this new landing page and render it in traditional portal. I tried implementing it but looks like the landing page renders blank. Just want to check with experts if I missed anything. In tracer we see rule not found exception for ‘CoexistenceCasesDT’.
We are OnPrem and recently upgraded to 24.1.3. Below are the steps which we followed-
Set the CDN DSS.
In Application definition enable to render landing pages in constellation.
Used App Studio to create a new landing page.
In app studio for portal navigation hit on Update Portal when we saw this message - This portal uses static navigation. Update the portal to use auto generated dynamic navigation. After this I saw my existing landing pages were missing. Potentially i need to add them back to the new navigation - was hoping it to be automatic.
In app studio added this new landing page to the navigation.
In my new landing page we created a view which displayed a table where data is sourced from a data page(local data storage).
When i click on this landing page - we just see coloumns and no rows.
@DhananjayU a complex area, IF this is your first Constellation app in this environment, I would be raising a Pega Support ticket so you can get detailed troubelshooting advice based on your configuration.
A few thoughts, without seeing your configuration its hard to narrow it down:
CoexistenceCasesDT is probably red herring, common error in tracer but I don’t think its blocking your page loading. That is usually security (see below / are you using OAuth 2?) or the configuration of the Constellation View.
On-prem - there are extra steps you have to go through to get this working on-prem. Constellation is more than just UI, its an architecture change. You’ve covered off the CDN DSS, but have you stood up your own CDN?
Constellation native app - I’d check if a Constellation app is working without the Traditional or Landing Page elements. Does a Constellation app work in your environment?
CSP - assuming no to 2 and 1 is setup correctly, the Content Security Policy for Constellation needs to be setup correctly. Especially, if you are On-Prem and 24.x, it could be that the CSP is blocking Constellation running correctly. In '25, Pega has an OOTB provided CSP for Constellation apps but in '24 and prior, you had to configure this yourself. It was a common pain point in your first adoption (along with the right DSS for your CDN and AppStatic)
Landing Page - Let’s assume its all working and its the Landing Page element that is causing the issue. First of all, I would test to see if the OOTB provided Explore Data landing page works in your Traditional App. This would eliminate your configuration as being the issue, just to see if your blending of UIs is working.
If your access groups are old, they might not have the Explore Data priveleges, this could stop that landing page opening too, so its not a 100% perfect way to check. I did post a while back on getting this working, that might help too Enabling Insights for Dashboards and Home in UIKit | Pega Community
Datapage - Next, is your datapage, which was my first instinct as the problem. Is it queryable? Does the data load via response data transform? Constellation is new architecture so some investigations warranted there. Pegasystems Documentation
I’d try some other datapages or list views just to see if its running.
