Getting error when viewing the group URL (qrencode+Python3.10 compatibility problem)

[digitalblur]

After creating a group and viewing the group from the web page, the QR code is a broken image. When I view the QR code URL I get the error:
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

and logs show the errors below:

OS is a fresh Ubunto 20.04
Python version: 3.10.6

Followed install steps here for sogs-standalone:
https://docs.oxen.io/products-built-on-oxen/session/guides/open-group-setup

Any ideas? thx

I am having the same issue with sogs-proxied in Ubuntu 22.04, tested the apt package and the manual installation, with nginx and Caddy and Python 3.10.6.

It seems the issue here is a problem with something in the qrencode package (e.g. there's an Arch Linux bug report about it here: https://bugs.archlinux.org/task/73372). I think we need to switch to qrcode rather than qrencode for generating the QR code for better compatibility.
