Providers

Apache Airflow version

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

  1. Airflow version: 3.1.8
  2. Python version: 3.11
  3. Executor/environment: Celery
  4. 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).

The issue is localized to one file: providers/sftp/src/airflow/providers/sftp/sensors/sftp.py. At line 32, the import from airflow.utils.timezone should be replaced with airflow.sdk.timezone. Check for any other occurrences of deprecated imports in the same file or other SFTP provider files. No additional research is needed beyond the file mentioned.
