Troubleshooting "Invalid CSV field" and NullPointerException in IBM Process Mining 2.0.2 When Adding a New Event Log

  • 1.  Troubleshooting "Invalid CSV field" and NullPointerException in IBM Process Mining 2.0.2 When Adding a New Event Log

    Posted Fri October 24, 2025 01:20 PM

    I'm running IBM Process Mining version 2.0.2

    I want to add a new event log with an additional column. I followed the documentation's suggestion, added a new column at the end of the previous CSV line, and encountered a problem. From the GUI, I'm getting "Invalid CSV field {0}" notification, and from the pm-app-web log file, it shows: 

    java.lang.NullPointerException: Cannot invoke "com.invenio.core.domain.PoolsContainer.getCsvMapping()" because "poolsContainer" is null

    Unfortunately, I don't know what causes an error. Do you have any suggestions on what could be wrong or what other files I should check to solve my problem?

    Hi Dawid, 

    The stacktrace is incomplete. Could you attach the entire stacktrace?
    Otherwise, I suggest you open a support ticket.

    Thanks.

    Hi Dawid, 

    the problem seems to be related to the fact that a GET is made of an object table that does not exist, that's why it throws a null pointer exception.

    Are you calling the service with the integration APIs?

    In any case, I suggest you open a support ticket here
