No idea why this is happening, the POST /api/v2/wfm/schedule/shift-swaps endpoint returns a 400 Bad Request when validating shift trades for our Chicago team. The payload matches the schema exactly, yet the error message cites an invalid start_time format that clearly adheres to ISO 8601 standards in the America/Chicago timezone.
The issue persists across multiple agent pairs during our weekly publishing cycle. We are using the latest SDK version and have verified the schedule window is open for modifications.
Any insights on hidden validation rules or timezone conversion bugs in the WFM module that might trigger this specific error?
