I'm using ExternalTaskSensor and the task just keeps poking

Question

I have two DAGs to test the use of ExternalTaskSensor

However, the ExternalTaskSensortask just keeps saying Poking and doesn't finish.

What could be happening?

enter image description here

These are my DAGs:

from datetime import timedelta, datetime
import pendulum
from airflow.models import DAG
from airflow.operators.bash import BashOperator
from airflow.operators.empty import EmptyOperator

dag_id = 'teste_dagA'

default_args = {
    'owner': 'Engineering',
    'retries': 2,
    'retry_delay': timedelta(minutes=1),
    'depends_on_past': False,
    'email_on_failure': False,
    'email_on_retry': False,
}

with DAG(
    dag_id=dag_id,
    tags=['teste', 'lakehouse', 'mediator'],
    default_args=default_args,
    description='teste',
    schedule_interval=timedelta(minutes=3),  
    start_date=datetime(2025, 1, 15,0,0,0), 
    catchup=False,
) as dag:

    empty_start_task = EmptyOperator(task_id='empty-start-task')

    empty_end_task = BashOperator(
        task_id='end',
        bash_command='echo "Tarefa concluída com sucesso!"'
    )

    empty_start_task >> empty_end_task

from datetime import timedelta, datetime
import pendulum
from airflow.models import DAG
from airflow.operators.empty import EmptyOperator
from airflow.sensors.external_task import ExternalTaskSensor

dag_id = 'teste_mediator'

default_args = {
    'owner': 'Engineering',
    'retries': 2,
    'retry_delay': timedelta(minutes=1),
    'depends_on_past': False,
    'email_on_failure': False,
    'email_on_retry': False,
}

with DAG(
    dag_id=dag_id,
    tags=['teste', 'lakehouse', 'mediator'],
    default_args=default_args,
    description='teste',
    schedule_interval=timedelta(minutes=3),  
    start_date=datetime(2025, 1, 15,0,0,0), 
    catchup=False,
) as dag:

    waiting = ExternalTaskSensor(
        task_id='waiting',
        external_dag_id='teste_dagA',
        external_task_id='end',
        execution_delta=timedelta(minutes=2)
    )

    empty_end_task = EmptyOperator(task_id='empty-end-task')

    waiting >> empty_end_task

If anyone understands the problem, I appreciate it.

I have already made some changes with execution_delta, but without success.

I am trying to understand the solution to my problem
