ZWave unavailable / Upgrade from 2023.7.2 to 2024.10.3

Configuration Z-Wave

I have this error:

2024-10-25 17:49:31.128 ERROR (MainThread) [homeassistant.config_entries] Error importing platform config_flow from integration zwave_js to set up zwave_js configuration entry: Platform zwave_js.config_flow not found
2024-10-25 17:49:35.932 ERROR (MainThread) [homeassistant.config_entries] Error occurred loading flow for integration zwave_js: Platform zwave_js.config_flow not found

ZWave JS is available:

homeassistant:~/.homeassistant$ telnet localhost 3000
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

(ZWave JS outputs a lot of info from the devices, as before).

More details from home-assistant.log:

The above exception was the direct cause of the following exception:

Any idea how to debug this?

Thank you.

Given the error ModuleNotFoundError it looks like there may be an installation issue. Seems you are using a Core install and not Container or Operating System? Does the file config_flow.py even exist in zwave_js component directory?

Yes, it is a manual installation. As there was a doubt about it, I redid the installation and copied the configuration.

Now, the above error is no longer present: there is a much more informative error message about my ZWave JS Server which apparently is too old for this HA release, so I will upgrade that and come again if I have any issue.

Thank you for your time.

Works with upgraded ZWave JS Server.
