Я пытаюсь написать простой код, который отправит некоторые показатели в приложении в облако Grafana. Я использую Python3.8 с библиотекой prometheus_client. Мое приложение не должно быть очищено, поэтому я не развертываю локальный экземпляр Prometheus и не использую prometheus_client.push_to_gateway() для прямой отправки данных в Prometheus Графаны. Проблема заключается в ошибке «HTTP 404 не найден», которую я получаю каждый раз, когда пытаюсь передать данные. В чем здесь может быть проблема?

Код:

 from prometheus_client import CollectorRegistry, Gauge, push_to_gateway
from prometheus_client.exposition import basic_auth_handler


if __name__ == '__main__':
    registry = CollectorRegistry()
    def my_auth_handler(url, method, timeout, headers, data):
        username = <MyUsername>
        password = <MyGrafanaCloudKey>
        return basic_auth_handler(url, method, timeout, headers, data, username, password)

    g = Gauge('job_last_success_unixtime', 'Last time a batch job successfully finished', registry=registry)
    g.set_to_current_time()

    push_to_gateway('https://prometheus-us-central1.grafana.net/api/prom/push',
                    job='TestJob',
                    registry=registry,
                    handler=my_auth_handler)
 

Ошибка:
