SNOW-2055494: Latest version throwing issue to import InstanceMetadataRegionFetcher

[sandeep-ahuja]

Python version

3.14.1

Operating system and processor architecture

AWS_DatabricksJob

Installed packages

pip install snowflake-connector-python

What did you do?

ImportError: cannot import name 'InstanceMetadataRegionFetcher' from 'botocore.utils' (/local_disk0/.ephemeral_nfs/cluster_libraries/python/lib/python3.11/site-packages/botocore/utils.py)
Workload failed, see run output for details

from ..wif_util import (
   AttestationProvider,
   WorkloadIdentityAttestation,
   create_attestation,
)

Received error at this line in source code:
https://github.com/snowflakedb/snowflake-connector-python/blob/main/src/snowflake/connector/wif_util.py#L14

To fix this, just gave specific previous version and it worked fine.
pip install snowflake-connector-python==3.14.0

What did you expect to see?

The import should happen as expected without any errors.
The newer version be backward compatible.

Can you set logging to DEBUG and collect the logs?

import logging
import os

for logger_name in ('snowflake.connector',):
    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)

I have the same issue with python 3.11.11

boto3==1.15.18
botocore==1.18.18
snowflake-connector-python==3.14.1
snowflake-sqlalchemy==1.7.3

I can reproduce it with the following script

import logging
import os

for logger_name in ('snowflake.connector',):
    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)

import snowflake.connector

which produces the output

Thanks for raising the issue and apologies. It's a bug on our end - the requirement for botocore version is too low. As a workaround I suggest to do:
pip install botocore\>=1.24
For the next release we'll bump up the minimum version requirement appropriately.
