CptTZ opened a new issue, #34641:
URL: https://github.com/apache/airflow/issues/34641
### Apache Airflow version
2.7.1
### What happened
I have a PythonOperator using a dictionary as `op_args`. When I enable
`render_template_as_native_obj`, a string value (but only with numeric chars,
i.e. `"life": "42"`) in the dict will be converted to int.
I did more researches and it seems the root cause is with `py` as
`template_fields_renderers`. I didn't look further into Airflow implementation
but I can help with debugging.
### What you think should happen instead
No field type conversion should ever happen.
### How to reproduce
DAG file:
```python
from datetime import datetime
from airflow import DAG
from airflow.operators.python import PythonOperator
from airflow.operators.smooth import SmoothOperator
BUGGY_DICT = {
"t1": 123,
"t4": "GOOD STR",
"life": "42",
}
def a_py_fun(a):
print(f"XX: {a}")
print(f"XX type: {type(a['life'])}")
with DAG(
dag_id='test',
schedule=None,
start_date=datetime(2023, 1, 1),
catchup=False,
render_template_as_native_obj=True, # Or False
) as dag:
d = PythonOperator(
task_id="py_bug",
python_callable=a_py_fun,
op_args=[BUGGY_DICT],
)
d >> SmoothOperator(task_id="xxx")
if __name__ == "__main__":
dag.test()
```
---
When `render_template_as_native_obj` is `True`:
```
...
XX: {'t1': 123, 't4': 'GOOD STR', 'life': 42}
XX type: <class 'int'>
...
```
When `render_template_as_native_obj` is `False`:
```
...
XX: {'t1': 123, 't4': 'GOOD STR', 'life': '42'}
XX type: <class 'str'>
...
```
