Erro na execução do twitter_hook.py

Olá Rafel!

Peguei o código no seguinte link: https://github.com/alura-cursos/alura-data-pipeline/tree/Aula-2

Quando executo o twitter_hook.py retorna o seguinte erro:

Traceback (most recent call last):
  File "twitter_hook.py", line 60, in <module>
    for pg in TwitterHook("AluraOnline").run():
  File "twitter_hook.py", line 53, in run
    session = self.get_conn()
  File "/Users/ralph/anaconda3/lib/python3.8/site-packages/airflow/providers/http/hooks/http.py", line 72, in get_conn
    conn = self.get_connection(self.http_conn_id)
  File "/Users/ralph/anaconda3/lib/python3.8/site-packages/airflow/hooks/base.py", line 63, in get_connection
    conn = Connection.get_connection_from_secrets(conn_id)
  File "/Users/ralph/anaconda3/lib/python3.8/site-packages/airflow/models/connection.py", line 354, in get_connection_from_secrets
    raise AirflowNotFoundException(f"The conn_id `{conn_id}` isn't defined")
airflow.exceptions.AirflowNotFoundException: The conn_id `twitter_default` isn't defined

Tentei comentar somente o "or "twitter_default"" na linha 10, mas retornou o seguinte erro:

Perhaps you meant http:///2/tweets/search/recent?query=AluraOnline&tweet.fields=author_id,conversation_id,created_at,id,in_reply_to_user_id,public_metrics,text&expansions=author_id&user.fields=id,name,username,created_at?

Desde já agradeço.
