      My service is using pymongo module for DB operations. With upgrade to pymongo 4.0.1 we are facing error for API insert_one, traceback captured belo. This error happens when the service runs in docker using 'python:3.10.1-bullseye' as base image. There is no issue observed if the pymongo version is 3.12.3. There is a similar issue reported for this error: https://jira.mongodb.org/browse/PYTHON-3029 

      Kindly let us know the resolution for this issue. Thanks!
