【app-functions-sdk-python】custom configuration issues

[yqhsmile]

How can I solve the problem of custom configuration when I am developing an application using Python's app functions SDK app-functions-sdk-python?

level=INFO ts=2026-01-23 16:17:45,976 app=app-collaborative-control source=logger.py:143 msg=Skipping use of Configuration Provider for custom configuration: Provider not available
level=ERROR ts=2026-01-23 16:17:45,979 app=app-collaborative-control source=logger.py:155 msg=Failed to load custom config: Incorrect type for field 'belts': expected typing.List[core.config.custom_config.BeltConfig], got <class 'list'>
