Real-time queue observation 404 on /api/v2/analytics/queues/realtime

Trying to pull live queue stats (waiting count, agents available) via the Statistics API. The UI shows the data fine, but the endpoint keeps returning 404. We’re using the Python SDK to hit /api/v2/analytics/queues/realtime. Here’s the request:

from genesyscloud import analytics_api_client

analytics = analytics_api_client.AnalyticsApi(api_client)
response = analytics.get_analytics_queues_realtime(
 interval="2023-10-27T08:00:00Z/2023-10-27T08:05:00Z",
 view="default",
 queue_ids=["queue-id-123"]
)

The docs say this is the right endpoint for real-time observation data. The 404 response body is empty. We’ve verified the OAuth token has analytics:report:read scope. The queue ID is correct and active. Tried swapping view to summary but same result. Is there a specific permission or API version flag needed for real-time endpoints? The standard historical query works fine on /api/v2/analytics/queues/data.
