-----------------------------------------
Hi RaviG! Assigning back to you! I was wondering if
Task20LineHistoryEventEmitter should not parse the failedDueToAttempt as well?
I used your patch, and a problematic jobhistory file was succesfully converted
to a trace file. However, will using a null cause any problems later while
running the trace?
