Python library openstacksdk not working with versions 5.x

[raddiana]

Hello,

Using openstacksdk to manage our infrastructure, we have noticed it does not work as expected with versions 5.x.
Here you can find the decorator that breaks: https://github.com/openstack/openstacksdk/blob/master/openstack/cloud/_utils.py#L387
For this function: https://github.com/openstack/openstacksdk/blob/master/openstack/cloud/_identity.py#L35

And this is the error we are getting:

What I need is a self-contained small script that exhibits the error.

Using decoratorx introduced in 5.1.0 could help in your case too (see #129).

Closing since I did not hear any more feedback in 6+ months.
