[aambroze]

(report re-written to reflect actual issue, pointed out by @agners)

Configuring wlan using ha network update without providing all required parameters causes internal server error with no feedback to the user.

What type of installation are you running?

Home Assistant OS

Which operating system are you running on?

Steps to reproduce the issue

1. Try to configure wlan adapter from shell without providing required parameters

Anything in the Supervisor logs that might be useful for us?

Additional information

No response

[agners]

The network configuration has no WiFi mode/SSID/authentication information, that is why that stack trace is caused.

Granted, Supervisor should handle this a bit more gracefully and send back an appropriate error.

But when passing WiFi information (--wifi-auth, --wifi-mode, --wifi-psk and --wifi-ssid), things should work again.

[aambroze]

I’ll try.

Even if that’s the case and it’s about providing proper network details and not graceful response…

Is it expected that my network details can be wiped during update from 11.5 to 12.1? Maybe that’s my actual issue ?

@agners
Thank you for suggestion.

I've connected using Ethernet and successfully enabled and connected to WiFi.

This leaves us with two issues:

• very ungraceful Supervisor behavior (crash/500 instead of simple information about required params),
• updating HAOS from 11.5 to 12.1 wipes WLAN details.

I'll redact my report to reflect the first issue. Where should I report second one?

This would go to the Home Assistant Operating System repository.
