Quick question about the bulk export API behavior for digital channels.
Background
We are exporting webchat transcripts for a legal discovery request in Europe/London. The environment uses BYOC S3 storage.
Issue
The POST request to /api/v2/analytics/conversations/export returns a 422 Unprocessable Entity. The payload specifies media_type as webchat, but the error indicates a validation failure on the date range format.
Troubleshooting
We verified the ISO 8601 timestamps. The issue persists even when narrowing the window to 24 hours. Is there a specific constraint on digital channel exports in this region?
