"warning: no page layout found" when clicking into an application/namespace

I am logged in as a super admin user, and this issue particularly only happens to one of the application/namespace but not others.

The error message just shows up fleetingly, and then immediately redirects me back to the home screen.

Is there any way to see more logging? I don’t see any errors in the browser console nor in the server logs. How to debug this further?

Thank you for the help.

You either don’t have any pages or are not allowed to access the pages(page layouts) you have.

Navigate to the namespace edit screen (where you can set its name and description). You should see the “Manage Namespace” button in the top right.
That will take you to the admin section of the namespace. You should check your pages/page layouts and their expressions.
