HttpSensor if endpoint not accessible or conn is wrong/not defined then do not go into next task

Question

I have following DAG below. My concern is about HttpSensor. My target is if the endpoint is not accessible for whatever reason i do not want want the next task to be reached get_data. Moreover i would like sensor to check enpoint continously and only if endpoint is reachable then go to get_data task. What i observed at the moment is get_data is reached even if sensor do not reach endpoint or conn is no defined, then get_data is anyway reached. How to solve that?

def get_data():
    response = requests.get("https://exampleweb/dis")

    if (response.status_code == 200):
        print("The request was a success!")
        print(response.json()) # Return a string representation of the data payload
    elif (response.status_code == 404):
        print("Result not found!")

with DAG(
         dag_id='request_test',
         schedule_interval=None,
         start_date=days_ago(2)) as dag:

    task_is_api_active = HttpSensor(
        task_id='is_api_active',
        http_conn_id='someconn',
        endpoint='exact'
    )

    get_data = PythonOperator(task_id="get_data",
                                  python_callable=get_data)

    task_is_api_active >> get_data
