Script update POST 429s at 5 RPS

Dealing with a very strange bug here with POST /api/v2/scripts returning 429 errors immediately after hitting 5 requests per second. Running JMeter 5.6.2 against Genesys Cloud BYOC Edge 24.1.0 in Asia/Singapore. The test plan uses a simple loop controller to create dummy scripts for load testing purposes. Each request includes a minimal JSON payload with just a name and description. The thread group is configured with 10 concurrent users, each ramping up over 2 seconds. The target endpoint is consistently throttled even though other endpoints like GET /api/v2/users seem fine. Is there a specific rate limit for script creation that differs from general API limits? The error response includes a Retry-After header set to 1 second. We are trying to determine if this is a platform-wide limit or specific to the scripting module. Any insights on how to handle this in our load testing strategy would be appreciated.
