DHBhensdadia opened a new pull request, #71328: URL: https://github.com/apache/airflow/pull/71328
`_python_type_from_string` maps OpenAPI parameter annotations to the argparse `type=` callable used by auto-generated commands. `datetime.date` was mapped to the class itself, but argparse calls that callable with the raw string from the command line and `date.__init__` expects three integers, so every value was rejected: ``` $ airflowctl dagrun list --partition-date-gte 2026-07-01 argument --partition-date-gte: invalid date value: '2026-07-01' ``` The message reads as a complaint about the format, but no input can succeed. `_is_primitive_type` accepts `datetime.date`, and `DagRunOperations.list` declares `partition_date_gte` and `partition_date_lte` as `datetime.date | None`, so this affects the shipped CLI. The hand-written commands in `dag_command.py` already parse these values with `date.fromisoformat`; the generated path had no equivalent. This adds `iso_date_type` alongside the existing `json_dict_type` and wires it into the mapping, so a valid value is parsed into a `date` and an invalid one reports the format that is actually expected. `datetime.datetime` has the same root cause but is left untouched here, since #70249 and #70250 are already open against it. The remaining constructor entries (`bytes`, `list`, `tuple`, `set`) are not reachable today, as no operation is annotated with them. related: #70232 --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes (please specify the tool below) Generated-by: Claude Code (Opus 5) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) --- * Read the **[Pull Request Guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#pull-request-guidelines)** for more information.
