uplsh580 opened a new issue #20646:
URL: https://github.com/apache/airflow/issues/20646
### Apache Airflow version
2.2.3 (latest released)
### What happened
To customize the operator, I inherited and customized the BashOperator.
It was used well in the previous 2.1.0 version without any problems, but an
error occurred in the 2.2.3 version as follows.
```
Broken DAG: [/opt/airflow/dags/test_dag_custom_operator.py] Traceback (most
recent call last):
File "/opt/airflow/dags/test_dag_custom_operator.py", line 14, in <module>
t1 = CustomOperator(task_id="date_task", cmd="date")
File
"/home/airflow/.local/lib/python3.7/site-packages/airflow/models/baseoperator.py",
line 188, in apply_defaults
result = func(self, *args, **kwargs)
TypeError: __init__() got an unexpected keyword argument 'default_args'
```
### What you expected to happen

### How to reproduce
create DAG file as below.
`custom_operator.py`
``` python
from airflow.operators.bash import BashOperator
class CustomOperator(BashOperator):
def __init__(self, task_id: str, cmd: str):
super().__init__(task_id=task_id, bash_command=cmd)
```
`custom_operator_dag.py`
``` python
from datetime import datetime, timedelta
from airflow import DAG
from custom_operator import CustomOperator
default_args = {"owner": "uplsh", "retries": 1, "retry_delay":
timedelta(minutes=1), "xcom_push_flag": True}
with DAG(
"custom_operator",
default_args=default_args,
description="A print date",
schedule_interval=timedelta(seconds=20),
start_date=datetime(2021, 1, 1),
catchup=False,
) as dag:
t1 = CustomOperator(task_id="date_task", cmd="date")
```
