AttributeError: module 'ctypes' has no attribute 'HRESULT' on Python 3.14

[khashayarnaderehvandi-beep]

SSH Command version
1.0.1

Home Assistant version
2026.4.3

The integration fails to load with the error: Config flow could not be loaded: {"message":"Invalid handler specified"}.

Looking at the logs, there is a fatal AttributeError during the import of the integration's components. It appears that the dependency asyncssh (v2.22.0) triggers an import of fido2, which contains Windows-specific calls (ctypes.HRESULT) that are incompatible with Linux-based environments running Python 3.14.

AttributeError: module 'ctypes' has no attribute 'HRESULT'

I attempted a temporary workaround by downgrading asyncssh to 2.14.0 in manifest.json. This allowed the integration to load, but resulted in a new error when executing commands:
'SSHCompletedProcess' object has no attribute 'stdout'.

Expected behavior
The integration should load without errors on Python 3.14

[gensyn]

Hm, interesting. I am running with Python 3.14 on Linux without a problem. It might be difficult to trace the problem.

[khashayarnaderehvandi-beep]

If there's anything I can to help find the root cause, I'd be happy to. I finished including this integration in a dozen scripts - everything worked - and then this issue sort of came from nowhere.

[gensyn]

This is an issue with asyncssh. fido2 is not a direct dependency of asyncssh so not everyone has the problem but it seems to be present on your system and asyncssh tries to load it.
So you can either try to remove fido2 from your system or we have to wait for the next asyncssh release.

[khashayarnaderehvandi-beep]

Thanks. The copilot suggestion actually works fine for me at this point...

[gensyn]

Well yes, or you can do that. 😅

[khashayarnaderehvandi-beep]

I did and I'm humming along now, though it took some (not being a coder and all) :)
Thanks!

[Cimpel]

How did you apply the fix ?

[gensyn]

It reads like they edited the source files themself. If you feel confident with git, you can check out branch "copilot/fix-attributeerror-ctypes-hresult" of this repo. Or you can replace custom_components/ssh_command/coordinator.py in your Home Assistant config folder with this version.

[Cimpel]

Yes, I simply edited the file manually. In coordinator.py I made the following change (as suggested by copilot):
Right below

from __future__ import annotations

I added:

import sys
import logging

_LOGGER = logging.getLogger(__name__)

if sys.platform != "win32":
    try:
        import fido2.client.windows  # noqa: F401
    except (ImportError, OSError, AttributeError):
        sys.modules["fido2.client.windows"] = None

Saved and restarted HA. And that was it.
