Posted: 5 months agoyerrh PEGA replied to RaymondS7147Hi,Are you using any pre-processing Data Transforms/activities in the 1st step? If yes, could you pls check if there is any error by saving the activity/data transform. And if there are any unnecessary pages & classes try removing them and check. Posted: 5 months agokanap2 PEGA replied to RaymondS7147There might be a rule, which had class defined in pages and classes but doesn't exist. Could you please trace or check the log to identify the rule and make changes to it to resolve the issue.
