On Python 3.10.6

does anyone run into this? when just running the 1 minute client example script? Odd thing is this works fine on Windows python 3.10 but on Ubuntu 20.04 I run into this issue...

During handling of the above exception, another exception occurred:

Is anyone else running into this on Python 3.10? @stan-janssen can people attempt a PR to address issues? I run into this on Ubuntu 20.04 LTS trying to run the Open ADR VEN Client code.

I cannot reproduce this issue. I'm running Python 3.10 on Ubuntu 20.04 myself and the examples work fine. Have you tried installing openleadr into a new virtual environment to rule out any other conflicting dependencies?

Of course, PRs are always welcome.
