Minha primeira Dag não aparece na interface web, verifiquei alguns erros no terminal após ativar o standalone | Apache Airflow: orquestrando seu primeiro pipeline de dados

Segue os erros que aparecem no terminal:

Boa tarde!

Gostaria de relatar que talvez eu tenha um problema similar! Insira aqui a descrição dessa imagem para ajudar na acessibilidade

Ao iniciar o DAG, depois de debuggar e iniciar no terminal o airflow, me deparo com o erro acima.

Tive que relizar uma correção no codigo onde, relizei a mudança do comando days_ago, creio que nao mais disponível.

SEgue abaixo o codigo utilizado:

from airflow.models import dag
from datetime import datetime
from airflow.operators.empty import EmptyOperator
from airflow.operators.bash import BashOperator
with dag(
    'meu_primeiro_dag',
    start_date = datetime(2023, 1, 1),
    schedule_interval= '@daily',
    tags = ['alura','teste'],
) as dag:
    tarefa_1 = EmptyOperator(task_id= 'tarefa_1')
    tarefa_2 = EmptyOperator(task_id= 'tarefa_2')
    tarefa_3 = EmptyOperator(task_id= 'tarefa_3')
    tarefa_4 = BashOperator(
        task_id = 'cria_pasta'
        bash_command= 'mkdir -p "/home/bruno/Documents/airflowalura/pasta" '
    )
tarefa_1 >> [tarefa_2,tarefa_3]
tarefa_3 >> tarefa_4

Poderiam me auxliar?
