Based on two reports received today we've found a regression in process session handling in NiFi 1.13.1. This is fixed on main and we will have a 1.13.2 RC1 up for vote in a couple hours. The core issue found is https://issues.apache.org/jira/browse/NIFI-8337. This is the same root problem as reported with https://issues.apache.org/jira/browse/NIFI-8334 Thanks Joe
