Description

Selecting "Download flow" for a process group which generated the file:

simple_download_flow.json

Tried to import this into Registry:
./cli.sh demo quick-import -i /Users/andrew.lim/Downloads/simple_download_flow.json

But got this error:

ERROR: Error executing command 'quick-import' : null

Added -verbose and see this stack trace:
