Whe n using %{module_name} in hiera.yaml how can you specify it for 'puppet lookup' command?

edit

Hi,

I'm using puppet 4.9.4 / 4.10 and hiera 3.3.1 . I'd like to be able to lookup values (like we used to be able to do with hiera command) for debug/testing . While I can define facts and specify --facts facts.yaml on the 'puppet lookup command' I cannot find a way to set module_name (claims in can't be overridden though it also doesn't appear to have a value).

Thanks in advance,
