Configuration.host is really a URL not a host

The report uses Configuration with AdminApi->admin_apps_list, but names no source file or test. Reproduce the example with a URL-valued host, then trace how Configuration builds the request URL and verify the endpoint receives the intended request rather than returning HTML 404. Done means the reported URL form has defined, working behavior.

I passed host = 'https://domain.of.my.instance' to the Configuration object and all I got was a lousy HTML (t-shirt material right there).

import os
import sys
import authentik_client


def main():
    host = os.environ.get("AUTHENTIK_HOST")
    token = os.environ.get("AUTHENTIK_TOKEN")
    if not token:
        print("AUTHENTIK_TOKEN unset")
        sys.exit(1)

    if not host:
        print("AUTHENTIK_HOST unset")
        sys.exit(1)

    configuration = authentik_client.Configuration(
        host=host,
        access_token=token
    )

    with authentik_client.ApiClient(configuration) as api_client:
        # Create an instance of the API class
        api_instance = authentik_client.AdminApi(api_client)
        try:
            api_response = api_instance.admin_apps_list()
            print("The response of AdminApi->admin_apps_list:\n")
            print(api_response)
        except authentik_client.ApiException as e:
            print("Exception when calling AdminApi->admin_apps_list: %s\n" % e)


if __name__ == "__main__":
    main()

When invoking it I got:

python move-okta-app-to-authentik.py 
Exception when calling AdminApi->admin_apps_list: (404)
