SAS® Infrastructure for Risk Management job flows fail to open and NullPointerExceptions errors occur


After you apply the SAS® Web Application Server 9.47 Hot Fix M3B008, you are unable to open SAS Infrastructure for Risk Management job flows. 

When this issue occurs, an error similar to the following is displayed in the SASIRMServer.log:

IRM 08:02:14.386 [tomcat-http--44] ERROR [2648d141-93be-11f0-a752-005056b788af] com.sas.solutions.risk.irm.server.webdav.IrmWebdavServlet - Caught Exception when resolve path for resource /fa.rmc.2023.03/jobflow/Analytics/irmc_data_preparation.bpmn, userid: rgfadmin

There is no workaround for this issue.
