default_args = {
    'owner': 'airflow',
    'depends_on_past': False,
    'start_date': datetime(2022, 1, 1),
    'retries': 1,
    'retry_delay': timedelta(minutes=5),
}

dag = DAG(
    'example_http_operator',

)

def http_request(**kwargs):
    # Make an HTTP request to a specified URL
    url = 'https://example.com'
    response = requests.get(url)
    return response.status_code

http_sensor = HttpSensor(
