----------------------------------
Summary: Pasting PG under version control with missing registry
client causes issues
Key: NIFI-14625
URL: https://issues.apache.org/jira/browse/NIFI-14625
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 2.4.0
Reporter: Bryan Bende
Assignee: Bryan Bende
Copy a version controlled PG from one nifi instance to another and the PG will
show on the canvas with a ? since the registry client id does not exist on the
second instance. NiFi UI is still usable and you could perform Stop Version
Control on the PG (if a registry client exists), but while in this state the
overall flow.json is failing to save and if you continue making changes on the
canvas and NiFi restarts, all those changes will be lost including the pasted
PG. The logs will repeatedly print...
ERROR [Flow Service Tasks Thread-2] o.a.nifi.controller.StandardFlowService
Unable to save flow controller configuration java.lang.IllegalStateException:
Process Group refers to a Flow Registry with ID <id> but no Flow Registry
exists with that ID. Cannot resolve to a URL. at
