Did I do something wrong?

[pieterhijma]

I cannot reproduce. I'm going to create a new release and could you please test with that and let me know or close? Thanks in advance.

[prokoudine]

Sure, will happily test!

[pieterhijma]

I've created a new release.

[prokoudine]

Just in case, upgrading to the latest version hasn't resolved the issue. Still can't connect.

[pieterhijma]

That's weird. Could you please provide the version number of FreeCAD and the version listed in /home/alex/.local/share/FreeCAD/v1-2/Mod/Ondsel-Lens/package.xml. Could you please reproduce here how you installed the Ondsel Lens server? I don't use docker myself, so perhaps that is different.

[prokoudine]

<version>2025.12.22.01</version>

I used docker per the installation guide.

[pieterhijma]

I can't reproduce, unfortunately. Perhaps you can remove /home/alex/.cache/FreeCAD/Cache/Ondsel-Lens and try again? Which FreeCAD version do you have?

[prokoudine]

Perhaps you can remove /home/alex/.cache/FreeCAD/Cache/Ondsel-Lens and try again

Tried, no luck

Which FreeCAD version do you have?

Switched to prebuilt docker images, and I can finally log in.

[pieterhijma]

Any idea what could have been wrong? From the stacktrace it looked as if you got an empty string as response? I'll reopen to make sure that if we are in a similar situation, it doesn't crash.

I really have no clue, I'm sorry
