3.1.8
What happened and how to reproduce it?
Summary
Importing SFTPSensor (from apache-airflow-providers-sftp) on Airflow 3.1.8 with Python 3.11 causes DeprecatedImportWarning due to usage of airflow.utils.timezone in SFTP provider code.
Current Behavior
On importing or using SFTPSensor, log shows:
[2026-04-17 18:35:28] INFO - Filling up the DagBag from /mnt/local/airflow/dagcodes/dags/utility/test.py
[2026-04-17 18:35:28] WARNING - The airflow.utils.timezone.convert_to_utc attribute is deprecated. Please use 'airflow.sdk.timezone.convert_to_utc'. category=DeprecatedImportWarning
[2026-04-17 18:35:28] WARNING - The airflow.utils.timezone.convert_to_utc attribute is deprecated. Please use 'airflow.sdk.timezone.convert_to_utc'. category=DeprecatedImportWarning
[2026-04-17 18:35:28] WARNING - The airflow.utils.timezone.parse attribute is deprecated. Please use 'airflow.sdk.timezone.parse'. category=DeprecatedImportWarning
Reproduction Steps
- Airflow version:
3.1.8 - Python version:
3.11 - Executor/environment:
Celery - Minimal DAG:
from datetime import datetime
from airflow.sdk import DAG
from airflow.providers.sftp.sensors.sftp import SFTPSensor
with DAG(
dag_id="repro_sftp_timezone_warning",
start_date=datetime(2024, 1, 1),
schedule=None,
catchup=False,
):
SFTPSensor(
task_id="wait_for_file",
path="/tmp/somefile.txt",
sftp_conn_id="sftp_default",
)
Analysis
providers/sftp/src/airflow/providers/sftp/sensors/sftp.py imports deprecated timezone path. Link: sftp.py Same behavior observed in provider releases including apache-airflow-providers-sftp==5.7.0 and 5.7.3. Link: sftp_5.7.3.py
What you think should happen instead?
No DeprecatedImportWarning should be emitted from provider internals on Airflow 3.x. Replace deprecated airflow.utils.timezone imports/usages with airflow.sdk.timezone in SFTP provider sensor(s).
