The import had a few errors - which was expected. After the final step, 16 records were skipped and 156 errors were reported.But went ahead with it. After import the rules including the flows look normal.But I get the below exception when I try to launch the manager portal. I have attached the screen shots of the tracer and the exception. Any assistance in solving this would be greatly appreciated.** Exception thrown by "com.pegarules.generated.pega_uiengine_pzskinfua.pzSkinMethodBody"Regards,Rashmi ***Updated by Moderator: Marissa to update categories*** Low-Code App Development Installation and Deployment ×Close popoverFacebookTwitterLinkedinEmail Copy Link Copied!
