Stumbled on a weird bug today with the Architect API when simulating concurrent calls. The flow works fine at 10 TPS but drops to 503 errors at 50 TPS.
The error happens specifically on the /api/v2/architect/flows endpoint during the POST request. This is in the US East region.
My JMeter config uses a constant throughput timer. The payload is identical for every request. No authentication issues.
Is there a hard limit on flow execution requests per second for new tenants? The docs only mention general rate limits.
