WFM Schedule Publish API 409 Conflict on Shift Swap

My current config is completely failing after the Tuesday schedule push. Agents with shift swaps in Chicago are stuck in the digital queue despite showing ‘available’ in WFM. The /api/v2/wfm/schedules endpoint confirms the swap, but routing fails.

“errors”: [
{
“code”: 409,
“message”: “Conflict with existing schedule constraint”,
“parameter”: “shiftSwapId”
}
]
