URL: https://github.com/apache/airflow/issues/19716
### Apache Airflow version
2.2.2 (latest released)
### Operating System
Ubuntu 18.04.6
### Versions of Apache Airflow Providers
_No response_
### Deployment
Other Docker-based deployment
### Deployment details
_No response_
### What happened
The deprecated variable `execution_date` raises an error when used in an f
string template with date string formatting.
```python
In [1]: execution_date
DeprecationWarning: Accessing 'execution_date' from the template is
deprecated and will be removed in a future version. Please use 'logical_date'
or 'data_interval_start' instead.
Out[1]: <Proxy at 0x7fb6f9af81c0 wrapping DateTime(2021, 11, 18, 0, 0, 0,
tzinfo=Timezone('UTC')) at 0x7fb6f9aeff90 with factory <function
TaskInstance.get_template_context.<locals>.deprecated_proxy.<locals>.deprecated_func
at 0x7fb6f98699d0>>
In [2]: f"{execution_date:%Y-%m-%d}"
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
----> 1 f"{execution_date:%Y-%m-%d}"
TypeError: unsupported format string passed to Proxy.__format__
```
### What you expected to happen
Execution `f"{execution_date:%Y-%m-%d}"` should return a string and not
raise an error.
### How to reproduce
```python
from datetime import datetime
from airflow import DAG
from airflow.operators.python import PythonOperator
def test_str_fmt(execution_date: datetime):
return f"{execution_date:%Y-%m-%d}"
dag = DAG(
dag_id="Test_Date_String",
schedule_interval="@daily",
catchup=False,
default_args={
"depends_on_past": False,
"start_date": datetime(2021, 11, 1),
"email": None,
"email_on_failure": False,
"email_on_retry": False,
"retries": 0,
},
)
with dag:
test_task = PythonOperator(
task_id="test_task",
python_callable=test_str_fmt,
)
```
