Why does this setting trigger a 500 Internal Server Error when I attempt to create a campaign with 50k contacts via the REST API?
I am using the Genesys Cloud REST API v2 to programmatically set up load test scenarios. The endpoint POST /api/v2/outbound/campaigns works perfectly for lists under 10k rows. However, as soon as the contact list size hits 50k, the server returns a 500 error immediately. The JSON payload is valid and passes validation locally. I am running this from a Node.js script, not JMeter, so it is not a client-side timeout. The error response body is empty. Is there a hidden limit on the number of contacts that can be associated with a campaign during creation, or is this a bug in the outbound service? My environment is Genesys Cloud US1.
