Why is this setting causing POST /api/v2/predictivedialing/campaigns to return 400 Bad Request when increasing thread count in JMeter 5.6.2? Running from Singapore with concurrent load on platform_api endpoints.
The payload is identical to the docs but fails at 50 threads. Getting ‘invalid campaign configuration’ in the response body without specific field details.
Any ideas on rate limits or payload structure issues for predictive routing campaigns under load?
