`git flow support start` not working

[dragGH102]

System: Debian 9 (WSL on Windows 10)

git flow support start featX --showcommands

always gives:

Missing argument <base>
usage: git flow support start [-h] [-F] <version> <base>

I've also tried with

git flow support feature featX

I checked the configuration via

git flow config

and this is the output

Branch name for production releases: master Branch name for "next release" development: develop Feature branch prefix: feature/ Bugfix branch prefix: bugfix/ Release branch prefix: release/ Hotfix branch prefix: hotfix/ Support branch prefix: support/ Version tag prefix:

What default value for the missing <base> argument do you expect the command to use in its place, master?

Being that a support branch exists for applying hotfixes to previous releases and that there are usually many release tags and only one main branch, it seems reasonable for the git flow support start command to require one to specify which of those previous releases the new support branch should be based on.
