Step one: the proxy starts dumping 502 Bad Gateway after roughly forty iterations. Response body isn’t helpful. Just {"code": "ANALYTICS_QUERY_TIMEOUT", "message": "Aggregation backend exceeded processing threshold"}. Mic stays hot while the loop spins anyway. The flow needs to pull live queue performance stats every thirty seconds to adjust disposition codes dynamically. We’re wiring a REST Proxy SNIPPET action to hit GET /api/v2/analytics/details/realtime. Payload looks straightforward. group_by is set to agent, interval to 5m, and from/to cover the current window.
Checked the API docs. Rate limits for analytics endpoints sit at one hundred requests per minute. The flow is throttled to two per second, so we’re nowhere near the cap. Tried swapping group_by=agent to group_by=queue. The 502 vanishes instantly. Points to the agent-level aggregation hitting a hard timeout on the backend. Studio build is 2024.12.1, tenant is on CXone Cloud 23.10. The SNIPPET timeout is set to 30000ms. Lowering it just cuts the response short, throwing a generic 408 Request Timeout instead.
Logs in the Studio debug view show the request leaving the SNIPPET fine. Headers include X-Request-Id: a8f3c2-91b4-4e2a. The issue only appears when the group_by parameter targets individual agents across a queue with over three hundred seats. Looks like the aggregation engine can’t handle the cardinality spike. Maybe chunking the queue_id list or using the batch export endpoint instead. The /api/v2/analytics/details/bulk route takes forever to generate the CSV. Need the data in memory for the routing logic.
curl -X GET "https://api.nice.incontact.com/apis/2/analytics/details/realtime?group_by=agent&interval=5m&queue_id=12345"
{"code": "ANALYTICS_QUERY_TIMEOUT", "message": "Aggregation backend exceeded processing threshold"}
The flow just keeps retrying until the SNIPPET action hits its max attempt limit.
