Just a note to anyone who may have encountered this: https://github.com/apache/airflow/issues/11965 if you add

cattrs==1.0.0

to the pip_url for Airflow in meltano.yml the issue resolves.

@niall_woodward Thanks for sharing! In

discovery.yml

, we went with a different solution that makes it less likely that we'll run into a similar issue with a different airflow dependency in the future: https://gitlab.com/meltano/meltano/-/issues/2400#note_438674675

Ah hadn't spotted it was one you'd fixed. Nice 🙂
