Hi

We have upgraded our application to 8.51. One of the workflow after resolving the case the screen throws

Error

There has been an issue; please consult your system administrator

In that session everytime the case is opened we get the same error. If we log out and login and open the case no issue. Below is the log we see during error. Please assist.

@Arvind

Do you have a “Caused By” on your PegaRULES log? I don’t see any on your extarct. Can you share the full log maybe?

@MarcLasserre_GCS Hi .. I dont see Caused by in the logs. Attaching the log. The error is only in the upgraded environment. I did the same in 7.4, it didnt throw error.

@Arvind

Weird,

Is it an upgraded case as well or a brand new one? Do you have that for all cases coming from that specific workflow?

@Arvind Alert log

@MarcLasserre_GCS I found the issue. Its on one particular legacy workflow. There is a Java code to delete pages.We have removed the step to work.

Commented as removeclipboardpages.

String strPages = tools.getParamValue(“KeepPages”);
PRThread thread = tools.getThread();
java.util.Vector keepAllPages = new java.util.Vector();
keepAllPages.add(“pyPortal”);
String pages = strPages.split(“,”);
for (int i=0; i < pages.length; i++) keepAllPages.add(pages[i]);
thread.removeAllPages(keepAllPages);
