IN View Profile Send Message mojjs PEGA replied to venkat kaza Hi, Did you check if the rule is withdrawn or blocked for some reason. Or if the ruleset is included and accessible to the user facing the exception. ? If you observe the full stack trace in logs, you can find from where the rule is being referenced. You need to start debugging from there Posted: 1 year ago Posted: 27 Sep 2019 6:28 EDT × Close popover Abirami Muthusamy (mutha1) PEGA Technical Solutions Engineer Pegasystems Inc.

IN View Profile Send Message Rachit_Agarwal PEGA replied to venkat kaza Is this happening with only this section? Can you try to do a Private-Edit of pzAssemblePreprocess (RULE-HTML-Section), and then open this rule. You should be able to open this.
