In commit e80a1d5 CLI won't ask non-required parameters. qname is mandatory, yaml file will be fixed by @pujavs. To test create a test flow file /tmp/test.flow with the following content:

Flow test
    Basepath "hello"

in = { name: "John" }
RRF "index.ftlh" in

Log "Done!"
Finish "john_doe"

And run CLI as folows:
