 Usage: lightning model upload [OPTIONS] NAME

Try 'lightning model upload --help' for help.

Error: Missing argument 'NAME'.

seems to imply i need to supply lightning model upload <filename/dirname>, when in reality if i do that, it begins to upload my entire current directory. the NAME it expects is ORG-NAME/TEAMSPACE-NAME/MODEL-NAME with optional --path, defaulting to current directory (.).

after

upload path is mandatory, rather than defaulting to current directory (.)

if it's mandatory, it should be a positional argument. flags are meant to be optional (hence the name click.option :) )
