I am trying to apply “Flexible Heuristics Miner” algorithm to BPI Challenges event logs by means of a ProM6.4 Plugin namely “Mine for a Causal Net Using Heuristics Miner”. However, while it does not have any problem with the other BPI Challenges events logs, I receive java.lang.NullPointerException error, when I try to apply the algorithm on the two of BPI, Challenges event logs namely, BPIC17f and BPIC15f3.
I have attached the java version of my PC, employed event logs, and full error message achieved by running prom64.bat. I will very grateful if somebody could help me to solve this problem. (I have read the previous similar topics in the forum and I believe it is not because of my java version)
link to BPIC17f3 event log: https://melbourne.figshare.com/ndownloader/files/15070961 (I cannot attach it because of its size, I used it after adding artificial end events by "add artificial events" prom6.4 plugin)
