Analytics API 500 Error During High Concurrency Load Test US1

Internal Server Error 500 returned from /api/v2/analytics/interactions/details when querying more than 20 concurrent users.

We are running a JMeter 5.6 load test to validate reporting performance under peak conditions. The environment is US1. The test simulates 50 concurrent supervisors pulling real-time interaction details. When concurrency exceeds 20 threads, the API fails with 500 errors. Lower concurrency works fine. This suggests a capacity limit on the analytics service rather than a config error.

Here is the request payload used in the test:

request:
 method: POST
 url: /api/v2/analytics/interactions/details
 body:
 dateFrom: "2024-05-01T00:00:00Z"
 dateTo: "2024-05-01T23:59:59Z"
 groupings:
 - type: "queue"
 metrics:
 - name: "duration"
 pageSize: 100

The headers include valid OAuth2 tokens. The error response body is empty. Is there a known throughput limit for this endpoint? We need to ensure our reporting dashboard does not break during high-volume shifts. Any guidance on rate limits or retry strategies for analytics queries would be helpful.
