Apache Airflow version

3.1.0

If "Other Airflow 2/3 version" selected, which one?

No response

What happened?

If the structlog package version > 25.4.0 is installed the import of airflow.sdk does not work.

>>> import airflow.sdk

ImportError: cannot import name 'Styles' from 'structlog.dev' (/home/xxxxxxx/miniconda3/envs/airflow/lib/python3.12/site-packages/structlog/dev.py)

What you think should happen instead?

Import should work for structlog 25.5.0 as it does for version 25.4.0.

How to reproduce

Install Airflow with pip install apache-airflow==3.1.0, open REPL and try import airflow.sdk.

                  What you think should happen instead?
                  Import should work for structlog 25.5.0 as it does for version 25.4.0.
                  How to reproduce
                  Install Airflow with pip install apache-airflow==3.1.0, open REPL and try import airflow.sdk.

ImportError: cannot import name 'Styles' from 'structlog.dev' (/home/xxxxxxx/miniconda3/envs/airflow/lib/python3.12/site-packages/structlog/dev.py)

                              What you think should happen instead?
                              Import should work for structlog 25.5.0 as it does for version 25.4.0.
                              How to reproduce
                              Install Airflow with pip install apache-airflow==3.1.0, open REPL and try import airflow.sdk.
