Pydantic 2.12.0 implemented experimental Sentinel that requires newer version of typing extensions. Our migration scripts however downgrade airflow to 2.11.0 and since airflow 2.11 does not have pydantic specified as required dependency, it does not downgrade it - but it downgrades typing-extensions that are airflow dependency. This causes a mismatch between expected version of typing extensions by Pydantic (4.14.1) and the one that we have installed in airflow 2.11 (4.13.1). However - in fact - pydantic is a dependency of Airflow 2.11 - becuase serialization uses pydantic serializer in 2.11 and it fails being imported if typing extensions is too low. This is only a problem when downgrading to Airflow 2.11 with constraints when you do not specify pydantic as extra. This should be fixed in 2.11.1 as there constraints should include latest version of typing-extension and pydantic. For now - the fix is to add pydantic as extra when downgrading airflow to 2.11.0 (cherry picked from commit dfb24d74b968d9362d68db5c46b2e789584480fb) Co-authored-by: Jarek Potiuk <[email protected]> -- This is an automated message from the Apache Git Service.
