[Dúvida] The conn_id `twitter_default` isn't defined

Olá pessoal!

Após digitar o comando no terminal, o seguinte erro apareceu: "The conn_id twitter_default isn't defined", apesar de ela estar aparecendo no airflow. O que pode ser?

Aqui esta meu código:

twitter_operator.py:

sys.path.append("airflow_pipeline")

        self.query = query
        super().__init__(**kwargs)

    def execute(self, context):
        end_time = self.end_time
        start_time = self.start_time
        query = self.query

        with open("extract_twitter.json", "w") as file:
            for pg in TwitterHook(end_time, start_time, query).run():
                print(json.dump(pg, file, ensure_ascii=False))
                file.write("\n")

    end_time = datetime.now().strftime(TIMESTAMP_FORMAT)
    start_time = (datetime.now() + timedelta(-1)).date().strftime(TIMESTAMP_FORMAT)
    query = "data science"

        to.execute(ti.task_id)
