What causes this error?

The ad group’s scheduling parameters are invalid. This could mean the start date is in the past, the end date is before the start date, or the dayparting configuration contains malformed time slots.

How to fix it

1. Dates: Ensure schedule_start_time is in the future and schedule_end_time is after the start.
2. Format: Use ISO 8601 format or the specific format TikTok requires (typically YYYY-MM-DD HH:MM:SS).
3. Dayparting: Verify your dayparting JSON array contains valid hour ranges (0-23) and day indices (0-6).
