Pull Request Overview

This PR fixes an error in the create_test function when working with queries that include CTEs. The fix involves adding a default value to the pandas_timestamp_to_pydatetime function and updating how it's called to use explicit keyword arguments.

• Added default value None to the columns_to_types parameter
• Updated function call to use explicit keyword argument df= instead of positional argument
