I'm here to help! It sounds like you're encountering an issue with the PATCH request for updating an assistant where the API is requiring additional fields beyond "fileIds" and defaulting other fields if not specified. This behavior is not expected for a PATCH request, which typically allows partial updates without affecting unspecified fields.
To address this, I would recommend reviewing the API documentation for the Update Assistant endpoint to ensure that you are following the correct procedure. If the documentation does not clarify the required fields for a PATCH request or if the behavior you're experiencing contradicts the documentation, this might be an issue that needs to be looked into by the development team.
If you have access to the API documentation, please check the details for the Update Assistant endpoint. If the issue persists, it would be best to contact support with detailed information about the problem, including the request you're making and the response you're receiving, so they can investigate further.
If you need assistance in contacting support or if you have any other questions, please let me know!
