jtommi opened a new issue, #27328:
URL: https://github.com/apache/airflow/issues/27328
### Apache Airflow Provider(s)
sftp
### Versions of Apache Airflow Providers
apache-airflow-providers-sftp==4.1.0
### Apache Airflow version
2.4.2 Python 3.10
### Operating System
Debian 11 (Official docker image)
### Deployment
Docker-Compose
### Deployment details
Base image is apache/airflow:2.4.2-python3.10
### What happened
When combining Taskflow API and SFTPOperator, it throws an exception that
didn't happen with apache-airflow-providers-sftp 4.0.0
### What you think should happen instead
The DAG should work as expected
### How to reproduce
```python
import pendulum
from airflow import DAG
from airflow.decorators import task
from airflow.providers.sftp.operators.sftp import SFTPOperator
with DAG(
"example_sftp",
schedule="@once",
start_date=pendulum.datetime(2021, 1, 1, tz="UTC"),
catchup=False,
tags=["example"],
) as dag:
@task
def get_file_path():
return "test.csv"
local_filepath = get_file_path()
upload = SFTPOperator(
task_id=f"upload_file_to_sftp",
ssh_conn_id="sftp_connection",
local_filepath=local_filepath,
remote_filepath="test.csv",
)
```
### Anything else
```logs

```
It looks like the offending code was introduced in commit
