Скрипт Python: получение ошибки «pyhaystack.exception.AuthenticationProblem» с сервером Niagara AX

Я пытаюсь получить доступ к серверу Niagara AX с использованием аутентификации python, предоставленной в документации pyhaystack, но сталкиваюсь с ошибкой аутентификации.

Я пытался обратиться к документации по pyhaystack (https://pyhaystack.readthedocs.io/en/latest/connect.html#id3),, но не так много информации об аутентификации. Рассматриваемый сервер использует токен csrf при входе через веб-браузер. 

import pyhaystack
session = pyhaystack.connect(implementation='ax',
                             uri='http://xx.xx.xx.xx',
                                username='xxxxxx',
                                password='xxxxxx',
                                pint=True)

op = session.nav()
op.wait()
nav = op.result
print(nav)

Использование этого кода обеспечивает следующий вывод:

Мы можем войти на серверный портал через веб-браузер и успешно использовали запросы Selenium для извлечения данных. Мне интересно иметь возможность извлекать данные без дополнительных затрат при использовании браузера.

Что я делаю не так?
