Authentication Token Expired (390114) - Any solution for snowflake-sqlalchemy?

Please answer these questions before submitting your issue. Thanks!

1. What version of Python are you using (python --version)? Python 3

2. What operating system and processor architecture are you using (python -c 'import platform; print(platform.platform())')? Windows2012ServerR2 6.3.9600-SP0

3. What are the component versions in the environment (pip list)? flask SQLAlchemy snowflake-connector-python

4. What did you do? If possible, provide a recipe for reproducing the error. A complete runnable program is good.

from sqlalchemy import create_engine engine = create_engine(‘snowflake://<connection-string>’ ) connection = engine.connect() names = connection.execute_query(“select names from employees”)

def sensor(): “”" Function for scheduling purposes. “”" v = cursor.execute(“”“select 1"”") v = v.fetchall() print(v)

sched = BackgroundScheduler(daemon=True) sched.add_job(sensor,‘interval’,minutes=50) sched.start()

1. What did you expect to see? Expected connection to persist

2. What did you see instead? Authentication Token expired and connection was lost

3. Can you set logging to DEBUG and collect the logs?

import logging
import os

for logger_name in ['snowflake.sqlalchemy', 'snowflake.connector', 'botocore']: 
    logger = logging.getLogger(logger_name)
    logger.setLevel(logging.DEBUG)
    ch = logging.StreamHandler()
    ch.setLevel(logging.DEBUG)
    ch.setFormatter(logging.Formatter('%(asctime)s - %(threadName)s %(filename)s:%(lineno)d - %(funcName)s() - %(levelname)s - %(message)s'))
    logger.addHandler(ch)

Any update on this. Should we do an good old restart server after 3:59

does client_session_keep_alive mean that you get a “forever” token? I don’t like this, is there any option to refresh the token manually?
