AttributeError: 'EnvHandler' object has no attribute 'get_variable'

Hi!

I just tried setting this up by following the quick start.

When running, I get the following error message;

Traceback (most recent call last):
  File "/opt/WSDG/adiliuswsdg.py", line 180, in <module>
    webhallen_username = EnvHandler.get_variable("email")
AttributeError: 'EnvHandler' object has no attribute 'get_variable'

I have tried running it with and without arguments, such as -e myemail@domain.com -p mypassword, and -e myemail@domain.com -p mypassword -s STORE. They all give me the same error message.

Have you encountered this before?

I'm running it on Ubuntu Server 22.04.2.
