Problem Description

I have install and configured Cortex (application.conf) and Elasticsearch (elasticsearch.yml) files. I am trying to create an admin user in Cortex but receiving the following exception.

cortex_6/_update/admin?_source=true&refresh=wait_for&routing=admin&retry_on_conflict=5
StringEntity({"script":{"source":"ctx._source[\"password\"]=params.param0;ctx._source[\"updatedBy\"]=params.param1;ctx._source[\"updatedAt\"]=params.param2","params":{"param0":"냠頤垅┑蛟뜙䧙甶࿨䡃,d1020d264a4c9b602bf895a52711df4ae569c978ae5af2c47bde9754d375e3c3","param1":"init","param2":1643826406831}}},Some(application/json))
