What did you do?

We use the snowflake connector to run checks via Nagios. It worked fine with v3.8.1 so far, however after upgrading to 3.10.0 we started to see the following error:

(No output on stdout) stderr: Traceback (most recent call last):
File "/usr/lib64/nagios/plugins/check/check.py", line 15, in <module>
ctx = snowflake.connector.connect(
File "/opt/venv/lib64/python3.9/site-packages/snowflake/connector/__init__.py", line 55, in Connect
return SnowflakeConnection(**kwargs)

return self._accessor.stat(self)
PermissionError: [Errno 13] Permission denied: '/root/.config/snowflake/config.toml'

The code at this location looks like this:

config = configparser.ConfigParser()
config.read(os.getenv('SNOWFLAKE_CONFIG'))

ctx = snowflake.connector.connect(
    user=config['snowflake']['username'],
    password=config['snowflake']['password'],
    account='vp12345.eu-west-1'
)

What did you expect to see?

I'd like to see the connector continue working as it was before. It's not mentioned anywhere that the config file is mandatory and it would be great if that error could be catched gracefully.

Can you set logging to DEBUG and collect the logs?

Hello @der-eismann ,

You meant that before python connector 3.10.0, there was no need for a config file, and it was connecting fine, but now, with Python Connector 3.10.0, it's asking for a config file?
If yes, could you please capture the Python log with connector 3.8.1 and let us know?

Sujan
