Ignore this - it had nothing to do with registry or versions. Looks like I was just missing "view the component" permission on main canvas for the account that we use to deploy the flows.

I developed some flows on nifi 1.8.0 and committed them to nifi registry. Now I am trying to deploy them to the nifi node that runs nifi 1.9.1 using nifi cli.sh from toolkit. cli.sh nifi pg-import -b "4ffb0e6f-dc5d-4546-b11d-694bcca2f89b" -f "802aab58-32a3-457f-bfdd-f927699944b7" -fv 37 I got "ERROR: Error executing command 'pg-import' : Error creating process group: An unexpected error has occurred. Please check the logs for additional details." bucket id and flow id and version are valid and same import works fine for 1.8.0 node. There is nothing in nifi-app.log. I did notice that in the .snapshot file in github for the flow I am trying to import - below block exists for most of the parts of my flow where artifact version is saved as 1.8.0. "bundle" : { "artifact" : "nifi-standard-nar", "group" : "org.apache.nifi", "version" : "1.8.0" }, Is there a way to make pg-import ignore this? What is the recommended way to import 1.8.0 flows from nifi registry to 1.9.1 node? Thank you
