… to 0.41.0 (#69854) The pin was stuck at 0.33.0 because later releases change how use-default interacts with nullable/optional fields. Versions 0.42.2 through at least 0.67.0 widen JsonValue-backed fields to JsonValue | None, and 0.57.0+ additionally drops the = None default from nullable-optional fields, turning ~200 fields in the Task SDK Execution API client and the airflow-ctl API client from optional into required -- a breaking Pydantic v2 model-contract change. 0.41.0 is the newest release that still regenerates both clients with a diff limited to the generator version-comment line (plus one benign RootModel[list] -> RootModel[list[Any]] typing improvement in airflow-ctl's generated.py), so it unblocks the dependency without carrying either regression forward. Closes the datamodel-code-generator item from #69616. (cherry picked from commit 15a4478) Co-authored-by: hkr <104939283+harishkesavarao@users.noreply.github.com>

There was a problem hiding this comment.
Clean backport — the changed-file set matches #69854 on main exactly (airflow-ctl/pyproject.toml, both generated datamodel files, task-sdk/pyproject.toml, _generated.py, uv.lock), and the regenerated headers correctly record version: 0.41.0. CI green. Carries the datamodel-code-generator bump onto the release branch, which is what we want.

The pin was stuck at 0.33.0 because later releases change how
use-default interacts with nullable/optional fields. Versions 0.42.2
through at least 0.67.0 widen JsonValue-backed fields to
JsonValue | None, and 0.57.0+ additionally drops the = None default
from nullable-optional fields, turning ~200 fields in the Task SDK
Execution API client and the airflow-ctl API client from optional
into required -- a breaking Pydantic v2 model-contract change.
0.41.0 is the newest release that still regenerates both clients with
a diff limited to the generator version-comment line (plus one benign
RootModel[list] -> RootModel[list[Any]] typing improvement in
airflow-ctl's generated.py), so it unblocks the dependency without
carrying either regression forward.
Closes the datamodel-code-generator item from #69616.
