Hey everyone, I’ve run into a really strange issue when trying to apply wrap-up for outbound campaigns. JMeter 5.6.2 from Singapore is hitting the API and getting 400 Bad Request. Payload looks correct in Postman but fails under load.
{
"status": "COMPLETED",
"wrapupCode": "SURVEY_SENT",
"callResult": "CONTACTED"
}
Any ideas why this fails specifically during high concurrency?
