I think I figured it out… NullPointerException at FlowController.java:873 was the clue. https://github.com/apache/nifi/blob/b1500ad0317578f903a441d327f44af255015af7/nifi-framework-bundle/nifi-framework/nifi-framework-core/src/main/java/org/apache/nifi/controller/FlowController.java#L873 Even though documentations mention “default” values, I needed to actually *add* all the keys to the nifi.properties. [ec2-user@----------- nifi]$ cat ./conf/nifi.properties | grep -i --color=auto python # for python extensions nifi.python.command=/usr/bin/python3 nifi.python.extensions.source.directory.default=/opt/nifi/nifi-current/python_extensions nifi.python.working.directory=./work/python nifi.python.framework.source.directory=./python/framework nifi.python.max.processes.per.extension.type=10 nifi.python.max.processes=100
