Stuck on screen recording uploads failing with 500 Internal Server Error when running JMeter 5.6.2 tests against the us-east-1 edge. The POST /api/v2/recordings endpoint works fine for low concurrency but crashes when concurrent call volume exceeds 50. We are hitting this during load testing for capacity planning. Is there a known limit on recording upload throughput or a specific rate limit for the recording:created event processing? Any insights on tuning this would be appreciated.
It depends, but generally… the 500 usually stems from the storage backend choking on concurrent multipart uploads rather than a hard API limit. Check if your JMeter script is properly handling the Content-Length header and ensure recording:uploaded events aren’t triggering synchronous webhooks that block the thread pool.
