Screen Recording API 503 during JMeter load test

What’s the best way to handle 503 Service Unavailable when fetching recording metadata at scale? Running JMeter from Singapore targeting Genesys Cloud. Hitting /api/v2/recordings/jobs. Need to validate throughput limits for screen captures.

  1. Spawn 100 concurrent threads.
  2. Poll job status every 2s.
  3. Observe 503 errors after 30s.

Any config tweaks?
