Today while using insert functionality on Apex data loader to add event registrants list on Salesforce we received an error message "populateAttendee: execution of BeforeInsertcaused by: System.NullPointerException: Attempt to de-reference a null objectTrigger.populateAttendee: line 17, column 1" and were unable to upload.

Does someone has faced a similar issue or can shed some light on this error message?

Thanks,
