python error when attempting to start

[swensonator]

Trying to run asksonic with navidrome. I have swag running for my reverse proxy and it works as expected on port 443.

I get the following error, regardless of whether I run asksonic locally or on Heroku.

Before I started trying to debug the code myself, I figured I would ask here.

It's due to your environment being Python 3.8; Asksonic requires 3.9. It should work in Heroku as the runtime.txt specifies 3.9.5. Is the error the same on Heroku?
