@18270704097, what does this example DAG look like? What does your project structure look like? Does this work with other versions of Airflow?

Already fixed in main in #52956

i tried to use

pip install "apache-airflow-providers-standard @ git+https://github.com/apache/airflow/#subdirectory=providers/standard"

to get #52956 into my airflow 3.0.2 but the error persisted
i guess this doesn't belong to the provider but the main code?
