Why

The original scripts might miss the case that the deferable argument is set as a positional argument. The following is an example operator that will pass this check.

from __future__ import annotations

from airflow.models.baseoperator import BaseOperator


class ExampleOperator(BaseOperator):
    def __init__(self, /, deferrable, *, a=1, **kwargs) -> None:
        super().__init__(**kwargs)

What

• add posonlyargs into check
• Check whether the argument default is not None when the argument is deferrable
