Cannot inspect members of docker client

I was trying to inspect the modules of the client object using inspect.getmembers when I got the following error:
I am using the master branch of docker-py, but the issue exists even on the stable 5.0.3 from pypi.

import docker
from inspect import getmembers

client = docker.from_env()
m = getmembers(client)
print(m)

Error:

Traceback (most recent call last):
  File "test.py", line 7, in <module>
    print(m)
  File "/Users/cozek/docker_api_work/docker-py/docker/models/resource.py", line 20, in __repr__
    return f"<{self.__class__.__name__}: {self.short_id}>"
  File "/Users/cozek/docker_api_work/docker-py/docker/models/resource.py", line 43, in short_id
    return self.id[:10]
TypeError: 'NoneType' object is not subscriptable

If you print the class name of the class whose id is NoneType, it is the Swarm class.
Supposed to be fixed in 2.6.0 as written
https://docker-py.readthedocs.io/en/stable/change-log.html?highlight=id

Fixed a bug where the id member on Swarm objects wasn’t being populated.

Workaround:

# `class Model` in resources.py
    @property
    def short_id(self):
        """
        The ID of the object, truncated to 10 characters.
        """
        return self.id[:10] if self.id else self.id

Now if you print the modules using inspect.getmodules you can see

...,('swarm', <Swarm: None>),('version', <bound method DockerClient.version of <docker.client.DockerClient object at 0x7f90fd06beb0>>), ('volumes', <docker.models.volumes.VolumeCollection object at 0x7f91006c4430>)]

Should I make a PR with the workaround, or is there a deeper fix ?

Start with docker/models/resource.py and the Model class in resources.py, then reproduce the issue with inspect.getmembers on a client created by docker.from_env(). Trace why the Swarm object's id is None and verify that inspecting the client no longer raises the reported TypeError.
