Pytest ERROR Unrecognized arguments from os.getenv addopts

Hi, I’m having trouble getting CircleCI config.yml to handle four command line arguments that my code sets through os.getenv as environment variables. I’m guessing that CircleCI can’t read the os.getenv addopts from the code and so flags the arguments as unrecognized.
While setting the os.getenv addopts as environment variables in CircleCI may allow them to get recognized, I don’t want to set the values there when I add them. The values need to be set at the command line.

Everything works as expected locally, and through Jenkins, but for a number of reasons we’re trying to move away from Jenkins.

Here is the error:

[percy] Running "pytest src/tests/ -v --baseurl=https://[redacted] --auth=https://[redacted]@[redacted] --site=4WP-US --env=UAT3"

And here are the relevant contents of

def pytest_addoption(parser):
    parser.addoption("--baseurl", action='store', default='https://[redacted]')
    parser.addoption("--auth", action='store', default='https://[redacted]@[redacted]')
    parser.addoption("--site", action='store', default='4WP-US')
    parser.addoption("--env", action='store', default='UAT3')
def pytest_configure(config):
    os.environ['baseurl'] = config.getoption('baseurl')
    os.environ['auth'] = config.getoption('auth')
    os.environ['site'] = config.getoption('site')
    os.environ['env'] = config.getoption('env')

Obviously I’m new to CircleCI and trying to get this off the ground. So far I’ve been unable to find anything in the documentation that helps with this specific use case.
