[bug#35950] [PATCH 2/3] gnu: python-flask-restful: Update to 0.12.1.

["Ludovic Courtès" <ludo@gnu.org>]

Hi Hamzeh,

The initial patch fails for me as well on

This confirms that we at least need ‘python-jsonschema’ as an extra
dependency, as Danny’s patch does.

Could you investigate and submit an updated patch?

Thank you,
