We did an in-place upgrade to 6.5 from 6.4.2. The pages are now not edit-able (even as an admin). I'm seeing this error:

Internal Server Error

Cannot serve request to /libs/wcm/core/content/pageinfo.json in com.day.cq.wcm.core.impl.servlets.PageInfoServlet

Exception:

java.lang.NullPointerException

This is the what i see when trying to load /libs/wcm/core/content/pageinfo.json:

      0 TIMER_START{Request Processing}
      0 COMMENT timer_end format is {<elapsed microseconds>,<timer name>} <optional message>

And here's the error :

24.04.2020 09:15:13.487 *WARN* [10.156.90.61 [1587683713197] GET /libs/wcm/core/content/pageinfo.json HTTP/1.1] com.adobe.granite.workflow.core.jcr.WorkflowModelManager Workflow model does not exist: /var/workflow/models/akamai/akamai-vod-delete

java.lang.NullPointerException: null

I think this is because there's RUNNING workflow instances for that a particular model that no longer exists.

I tried purging these workflows from the JMX console but no luck.
 

Thanks in advance,

Anjali

Unfortunately a NullPointer without any details (java file, line number) is really hard to debug, when you cannot attach a debugger to it.

 

Is the shared excerpt from the "recent requests" all what's logged? I don't see the error being logged.
