I am trying to mask Mainframe sequential file and during workflow generation I'm getting below error. Not able to find the reason of failure. I'm able to perform row test on mainframe file in power exchange without issue.
This is the error message "com.informatica.ilm.tdms.mapgen.executor.MappingGenerator [WF_EXCEPTION_00000] An Exception has occured. java.lang.NullPointerException: null"
