My executor is the CeleryExecutor,
and this is my test DAG:
`from airflow import DAG
from airflow.operators.python import PythonOperator
from datetime import datetime

# Função que será executada pela tarefa
def print_hello():
    print("Hello, Airflow!")

# Definição da DAG
with DAG(
    dag_id='test_hello_airflow',
    start_date=datetime(2025, 1, 1),  # Data inicial da DAG
    schedule_interval='@daily',  # Executa diariamente
    catchup=False,  # Não executar tarefas retroativas
) as dag:
    
    # Operador que executa a função Python
    hello_task = PythonOperator(
        task_id='say_hello',
        python_callable=print_hello
    )`
