alexandermalyga opened a new issue, #27081:
URL: https://github.com/apache/airflow/issues/27081
### Apache Airflow version
2.4.1
### What happened
When initialising an operator with multiple inheritance, an exception is
raised:
`airflow.exceptions.AirflowException: missing keyword argument ...`
This only happens when multiple parent classes share an attribute name in
their `__init__` method.
### What you think should happen instead
Multiple inheritance with shared attribute names in the parent classes
should work as expected in Python.
### How to reproduce
Run this python script:
```
from airflow.models import BaseOperator
class A(BaseOperator):
def __init__(self, *, value: str, **kwargs):
super().__init__(**kwargs)
class B(BaseOperator):
def __init__(self, *, value: str, **kwargs):
super().__init__(**kwargs)
class C(A, B):
def __init__(self, *, value: str, **kwargs):
super().__init__(value=value, **kwargs)
C(task_id="test", value="value")
```
### Operating System
macOS 12.6
### Versions of Apache Airflow Providers
_No response_
### Deployment
Docker-Compose
### Deployment details
_No response_
### Anything else
The issue seems to be somehow caused by the @apply_defaults decorator and
signature caching, but I'm not very familiar with it.
