Team, Following some messages in Slack, we found an issue related to properties migration on the scripted components [1]. Given how widely those components are used, I'll be starting a 2.7.1 release process later today including the fix and have a short 24 hours vote to get this fix out and avoid any impact for users migrating to the latest version.
Let me know if you have any questions, Thanks, Pierre [1] https://issues.apache.org/jira/browse/NIFI-15317
