Make edits to the Python script that exports data from Bitrix24

We have a custom script written in Python that exports data from various systems, including Bitrix24. Deals, leads, contacts, smart processes, lists, etc. are exported. After the Bitrix24 update, custom fields of the "Yes/No" type instead of 1/0 values began to accept Y/N values. Taking into account the above, it is necessary to make changes to the script so that the values of custom fields of the "Yes/No" type are passed in the form of 1/0.

For development, we provide RESTAPI access to the test B24, as well as to the project repository. ClickHouse can be used on a local server.

Preference is given to middle and higher developers with at least 4-5 years of experience in Python, who do not disdain to study someone elses code, and are also ready to help in further improvements to the script (there are still small tasks on the script, but after completing this task).
Experience with the Bitrix24 REST API is required (to understand the data received).
